2,000-seat cutover

Color-coded sequence: Source PBX → Plan → Cutover → Webex. A packet moves along the arrows. Reduced motion keeps every step visible.

T6-R01. A Canon planning room for a scenario: 2,000 seats on CUCM and UCCE, moving toward Webex Calling and Webex Contact Center. The seat count is the exercise, not a Cisco limit.

Reading 11 minDraftStudy notes

01 · TL;DR

Rebuild beside the old estate

Size trunks from concurrent calls. 2,000 seats is not 2,000 calls. [cite:2]
Do not import ICM scripts. The crosswalk stays marked in T6-R04. [cite:4]
Premises users cannot use cloud PSTN. [cite:3]
WebRTC agents do not go live before 933. [cite:7]
The runbook below is Canon planning.

02 · Map

Two migrations, one scenario

03 · Core

What you may claim

The calling half starts from the Unified CM migration introduction. It is not a CSS conversion table. [cite:1]

As of 2026-10-14, t9xctu Table 5 maps concurrent calls to a trunk preference: up to 250 registration-based OTT, about 250–2000 certificate-based OTT, about 2000–6500 certificate-based interconnect. A 2,000-seat office can sit in any row depending on busy-hour calls. [cite:2]

n0xb944 says calls originating from premises users cannot access cloud PSTN. Mixed sites need a premises path for the users who have not moved. [cite:3]

The contact-center half is T6-R04. Three tools exist, and none of them imports an ICM script. The CCX discovery tool is not pointed at a UCCE logger. Skill groups, peripherals, CUIC, Finesse, and UCCE dialed numbers stay marked there. [cite:4]

The objects you can build from the architecture article are the entry point, the flow, the queue, and the team. [cite:5]

04 · Ecosystem

Ecosystem and sister technologies

Mini map of the neighbors named on this room’s sequence. Orientation sketch, not a new product claim.

Scenario size: 2,000 seats is the design exercise in this room. It is not a Cisco limit and it is not a concurrent-call count.
Canon planning: The phase list and the cutover runbook below are a Canon method. Cisco has not published a 2,000-seat CUCM plus UCCE runbook in the articles this room cites.
PPDIO: The calling migration introduction is the door for Unified CM to Webex Calling. The contact-center cutover is not that article. [cite:1]
Concurrent calls: t9xctu Table 5, as of 2026-10-14: up to 250 concurrent prefers registration OTT; about 250–2000 prefers certificate OTT; about 2000–6500 prefers certificate interconnect. Size trunks from concurrent calls. [cite:2]
Premises PSTN limit: Calls that originate from premises users cannot use cloud PSTN. [cite:3]
CSS versus patterns: CUCM closest-match is the CallManager System Guide rule: every partition, closest match, order only as a tie-break. That is not the Webex wildcard engine. Field equivalence stays marked in T6-R02 and T2-R03. [cite:10]
No ICM import: None of the three published tools imports an ICM script into Flow Designer. Those rows stay marked in T6-R04. [cite:4]
CCX jar is not UCCE: 0hd75db is Unified CCX. Do not point it at a UCCE logger. [cite:4]
Entry point: The multi-tenant front door: entry point, flow, queue, team. [cite:5]
Pilot: The 1.0 article says test a few users before you move everyone. That article is inside WxCC 1.0, not UCCE. The Canon method copies the caution, not the product. [cite:6]
933 before agents: WebRTC agents need RedSky tested before they take live calls. [cite:7]
Recording choice: Quote both nhvl4hw defaults. Recording also disables Calling E2EE. [cite:8] [cite:9]
Analyzer versus CUIC: Canon planning: keep CUIC until a person compares one report. nb2ve0e cleanup makes legacy Analyzer data available. That article does not mention CUIC. The CUIC row stays marked in T6-R04. [cite:6]
Dual desktop: Finesse and Agent Desktop on the same UCCE call stays marked in T6-R04. This runbook does not schedule that coexistence.
Number move: Canon planning: move one number only after the new flow answers. Do not move numbers with the CCX workbook. That workbook is a CCX extract, cited from T6-R04.
Rollback: Leave the old route in place until the new path has answered a test call. Canon planning, not a Cisco command.

Sister-technology matrix

Sister	What it is	Why it matters	Config touchpoint	Typical failure	Cite
Unified CM	The 2,000-seat PBX in this scenario	CSS, partitions, and route patterns stay until you cut users.	T6-R02	Treating closest-match as the Webex dial plan.	[cite:1]

Analyzer and CUIC	Two reporters during coexistence	Compare by hand.	T3-R07 and T6-R04	Turning CUIC off on day one.	T3-R07
Workforce management	py6u9h, header June 09, 2026, lists minimum WFO SKUs for Webex Contact Center Enterprise, Contact Center Enterprise, and Contact Center Express. WFM Agent Assist requires the Full WFM SKU `A-FLEX-WFO-NWFM2`.	That scope sentence is not a multi-tenant order.	Read Table 1 in py6u9h before copying a SKU onto the new tenant.	Applying `A-FLEX-WFO-NWFM2` to multi-tenant because the cutover rebuilt the queues.	[cite:12]
Quality and recording	Calling recordings: Webex keeps them one year, 100 GB per organization. Dubber Go keeps each recording 30 days. Both “default” sentences are in nhvl4hw.	Read Webex Calling retention in nhvl4hw and the queue recording switch in the contact-center article. The clocks differ, which is why a Calling number is not the WxCC quality-management policy.	Pick the Calling provider in nhvl4hw. Leave the queue recording switch to the queue article.	Pasting one year or 30 days onto the contact-center QM policy.	[cite:9]
Analytics	Analyzer real-time reports remain available and refresh automatically. A new real-time report defaults to 5 seconds. The drop-down runs from 5 to 60 seconds in steps of 5. Historical reports stay active 8 hours.	CUIC stays up during coexistence. This clock is not a CUIC import.	Open stock reports under Visualizations. Excel or CSV export is for historical visualizations. Real-time and compound visualizations are not exported.	Turning CUIC off on day one, or calling a 60-second desktop widget this Analyzer default.	[cite:13]
CRM	Cisco’s Dynamics 365 connector uses CIF 1 for single-session apps and CIF 2 for multi-session apps. On-premises Dynamics is not supported.	This is a screen-pop connector. It is not Microsoft Dynamics 365 Contact Center.	Channel host `wxcc-crmconnectors.ciscoccservice.com`. Match CIF generation to the app type.	Pointing the connector at on-premises Dynamics.	[cite:14]
AI agents	s0qro1, header August 25, 2026, says access to the autonomous AI agent for voice calls is limited to specific customers.	The CCX discovery workbook does not create these agents.	Build the agent in its own article, then attach it. Do not expect the migration jar to do that.	Telling the pilot that the CCX zip imported an AI agent.	[cite:15]
Google CCAI	n6gaghu says to configure the Google CCAI connector in Control Hub, then create the Contact Center AI feature. The system generates a CCAI config ID for Flow Control.	Dialogflow CX and Dialogflow ES are that article. Webex AI agents are a separate article.	Connector, then CCAI configuration, then the config ID in the flow.	Looking for a Google CCAI node inside an ICM script.	[cite:16]
Amazon Connect	No Amazon Connect connector is named in the articles this room cites.	nbedetf is a Unified CM to Webex Calling migration. It is not a contact-center parity matrix.	Do not add an Amazon contact-flow import to the cutover list.	Treating an Amazon export as a Flow Designer file.	[cite:1]
Teams calling	n0l9q2z, header July 08, 2026, installs Cisco Call as the Teams calling app. Presence sync is a Control Hub toggle. A Unified CM backend in that article needs Unified CM 12.5 SU7 or 14 SU3.	This is calling inside Teams. It does not replace Agent Desktop or move an ICM script.	Teams admin: Teams apps > Manage apps, allow Cisco Call, then a setup policy that pins it. Control Hub: Webex App tab, Microsoft Teams integration, Presence sync.	Using Teams Phone as the contact-center desktop for this cut.	[cite:17]

WFO SKU rejected on the new tenant	py6u9h scopes those SKUs to Enterprise, CCE, and CCX.	The order type, not the queue name.	Do not copy `A-FLEX-WFO-NWFM2` onto multi-tenant from that table.	[cite:12]
Analyzer and CUIC disagree on day one	They are different reporters. Analyzer historical sessions last 8 hours. A new real-time report refreshes every 5 seconds unless you change the 5-to-60 drop-down.	Which tool printed the number.	Leave CUIC up and compare a named report by hand.	[cite:13]

05 · Flow

Phases

Inventory, Canon planning. List sites, CSS and partitions, route patterns, devices, and busy-hour concurrent calls. List UCCE dialed numbers, call types, skill groups, and scripts as names you will rebuild, not as objects a tool will convert. [cite:1] [cite:4]
Calling design. Follow the Unified CM migration introduction for users you intend to move. Keep CUCM closest-match out of the Webex pattern engine. [cite:1]
Trunk and PSTN. Choose registration or certificate from concurrent calls, not from 2,000 seats. Premises users do not get cloud PSTN. [cite:2] [cite:3]
Security choices before the pilot. Quote both recording defaults. If a call must be recorded, Calling E2EE is off. Build RedSky and pass 933 before any WebRTC agent is in the pilot. [cite:7] [cite:8] [cite:9]
Contact center beside the old estate. Create entry points, flows, queues, and teams. Do not run the CCX jar. Do not rename ICM nodes. [cite:4] [cite:5]
Pilot. A few agents, one flow, lab numbers. The caution to test a few users first is the WxCC 1.0 article, not a claim that UCCE uses that portal. [cite:6]
One number. Canon planning. Cut a single dialed number only after the new flow answers. Leave the old route until that call is logged.
Reports. Canon planning. Leave CUIC up. Compare a named report in Analyzer by hand. T3-R07 has the clocks. nb2ve0e does not convert CUIC. [cite:6]

Canon planning

Nothing in this list is a Cisco runbook. If a later article contradicts a step, the article wins and this page changes.

06 · Config

Cutover runbook

Freeze a window. Write the one number, the entry point, and the rollback route on one page.
Confirm RedSky from nvfbjts: 933 has been placed, Emergency call routing is the mode you intend, and each pilot agent’s identification type is Device User Id equal to the email. Header September 08, 2024. re-check [cite:7] mwjlgk, header September 03, 2025, is the agent install. It confirms https://wxc.e911cloud.com and a verification email. It does not replace those admin steps. [cite:11]
Confirm the flow is published and a lab call has reached an agent.
Move that one number. Place one test call. Save the result.
If the call fails, send it back to the route you did not delete. Do not debug by moving the rest of the range.
If the call succeeds, leave CUIC and the old scripts in place. Expand only after a written comparison.

This runbook is Canon planning. It is not nbedetf, not the CCX workbook, and not the WxCC 1.0 portal move.

Trouble

Symptom	Wrong story	What you can cite	Do this	Cite
The plan says 2,000 concurrent calls because there are 2,000 seats	Seats are not concurrent calls.	Size the trunk from busy-hour concurrent calls and t9xctu Table 5.	Rewrite the capacity slide.	[cite:2]
A registration trunk is ordered for the whole estate	Registration trunks stop at 250 concurrent calls.	Above that, the getting-started article says certificate-based.	Change the trunk type.	[cite:2]

09 · Self-question

Oral ladder

L1What is the 2,000?

A scenario size for this exercise. Not a Cisco limit.

L2Is this runbook a Cisco document?

No. It is marked Canon planning.

L3Where do Calling moves start?

The Unified CM migration introduction, T6-R02. [cite:1]

L4How do you size the trunk?

From concurrent calls, using t9xctu Table 5 as of 2026-10-14. [cite:2]

L5Can a CUCM phone use cloud PSTN?

No. Premises-originated calls cannot. [cite:3]

L6What does not import?

ICM scripts, CVP applications, skill groups, CUIC, Finesse gadgets. See T6-R04. [cite:4]

L7What do you build beside the old estate?

Entry points, flows, queues, and teams. [cite:5]

L8When do WebRTC agents go live?

After 933 and Emergency call routing. [cite:7]

L9What happens if you also want E2EE?

Recording disables it. Decide first. [cite:8]

L10How many numbers move in a step?

One, after that flow answers. Canon planning.

L11What stays up for reports?

CUIC, until a human comparison is written down.

L12What is the rollback?

The old route was not removed. Send the number back. Canon planning, not a Cisco command.

10 · Lab

Paper pilot

Write 2,000 seats on the left and a blank concurrent-call cell on the right. Do not copy the seat count across.
Pick a trunk row from t9xctu Table 5 only after you invent a busy-hour number and label it as a lab assumption.
List three UCCE nouns and write “marked in T6-R04” beside each.
Write the recording decision and the E2EE consequence on the same line.
Script a one-number cut and a rollback that uses the route you did not delete.
Break it: schedule Finesse and Agent Desktop on the same UCCE call. Recovery: delete that row.

Quiz

Q1MCQ

2,000 in this room means:

Answer

2,000 in this room means: Seats in a Canon planning scenario. Not concurrent calls and not a Cisco cap.

Q2Oral

Why is the runbook labeled Canon planning?

Answer

Why is the runbook labeled Canon planning: Cisco has not published this 2,000-seat CUCM plus UCCE procedure in the cited articles.

Q3MCQ

A registration trunk is appropriate when concurrent calls are:

Answer

A registration trunk is appropriate when concurrent calls are: Up to 250, in t9xctu Table 5. [cite:2]

Q4Scenario

The dial plan keeps 1,000 users on CUCM and sends their PSTN through Cisco Calling Plan.

Answer

Premises-originated calls cannot use cloud PSTN. [cite:3]

Q5MCQ

The CCX discovery tool belongs on:

Answer

Unified CCX. Not a UCCE logger. [cite:4]

Q6Oral

Name the WxCC objects you build beside UCCE.

Answer

Name the WxCC objects you build beside UCCE.: Entry point, flow, queue, team. [cite:5]

Q7Scenario

The pilot skips 933.

Answer

The pilot skips 933.: Stop. WebRTC emergency is nvfbjts. [cite:7]

Q8MCQ

Recording plus Calling E2EE:

Answer

Recording disables E2EE. [cite:8]

Q9Oral

What do you do with CUIC on cut night?

Answer

What do you do with CUIC on cut night: Leave it until Analyzer has been compared by hand.

Q10Scenario

Two desktops on one UCCE call.

Answer

Do not schedule Finesse and Agent Desktop on the same call. T6-R04 has no dual-desktop or shared-call article in its cites. Agents cannot use the legacy desktop and the new desktop at once, and that split is a profile flag.

Q11Draw it

Draw phases without dates.

Answer

Inventory, Calling design, Trunk and PSTN, Security choices before the pilot, Contact center beside the old estate, Pilot, One number, Reports. RedSky sits inside the security phase. These names are Canon planning.

Q12MCQ

Rollback in this room is:

Answer

Rollback in this room is: A Canon planning step: the old route is still there until you choose to remove it. Not a hidden Cisco command.

Oral-ready

30 seconds. I would not move 2,000 CUCM and UCCE seats with one tool. Calling follows the migration introduction. Contact center is rebuilt as entry points and flows. The cutover list in T6-R01 is Canon planning.

2 minutes. Trunks follow concurrent calls. Premises users cannot use cloud PSTN. I do not run the CCX jar on UCCE. I do not promise recording and Calling E2EE together. WebRTC agents wait for 933. CUIC stays until Analyzer is compared by hand. One number moves at a time.
