Migration Tools

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

Cisco documents three ways onto multi-tenant Webex Calling: Control Hub tools, certified migration providers, and Webex Setup Assist. The Control Hub user tool moves at most 1,000 users and 1,000 devices in one task. The feature tool does not currently build call park or call pickup. A Python script does.

01 · Executive summary

Five lines, then why it matters

Migration Insights can run from any organization. You do not need the destination customer org to upload a Unified CM tar. [cite:2]
Use SharedlineGroupMigrationReport.csv and HuntGroup_CallQueue_CallPark_CallPickUpGroups.csv to see who must move together. [cite:2]
A-FLEX-P-CALL is the entitlement the user-migration article names for temporary licensing from GLO, up to 18 months. [cite:2]
Feature-tool upload limits: Unified CM tar 350 MB, Unity call-handler zip 2 GB. [cite:3]
The Dedicated Instance pre-migration assistant is a different tile. It does not perform that migration. T5-R06. [cite:5]

Why it matters. Tool choice fails when a Standard license is forced through the user task, when call pickup is expected from the feature tool alone, or when an 8821 is put on the MPP list.

03 · Core concepts

Which tile does which job

Three families

The December 2025 deployment guide names Webex Migration Tools as self-service tools in Control Hub, Certified Migration Providers as validated software for complex and large migrations, and Webex Setup Assist as a Cisco-led service. [cite:1]

License the user tool will not assign

Users migrated with the Unified CM user tool can only be assigned Calling professional or CX Essentials. To assign a Webex Standard license, do not use this tool. Use a user CSV, then the feature tool for the rest. Workspaces can be Workspace or Professional Workspace. [cite:2]

Park and pickup

The feature article lists Call Park among mapped data, and the script section says the feature tool does not currently support CallPark.csv and CallPickupgroup.csv. The script UserBasedUCMFeatureMigration creates those files from CDR. Keep both sentences. [cite:3]

Dedicated Instance

The user-migration article and the firmware article each say the steps apply to Dedicated Instance. The pre-migration assistant is still a different tile and does not perform the Dedicated Instance migration. [cite:2] [cite:4] [cite:5]

Control Hub tools

Tool	Path the article prints	What you bring	Cite
Migration Insights	Services → Upgrades and Migrations → Migration Insights	Unified CM tar. CDR if you want feature-usage reports. Any org can host the assessment.	[cite:2]
Migrate Unified CM to Webex Calling	Services → Upgrades and Migrations → that tile	Tar from BAT, or a user CSV. Phones on load 14.1 or later. Users already in Webex.	[cite:2]
Migrate features from UCM	Services → Updates and Migrations → Migrate features from UCM. A later step in the same article says Migrate features from Unified CM.	Tar, optional Unity call-handler zip.	[cite:3]
Phone firmware	The firmware article. The implement article also names “Migrate your phone to Webex Calling” for 7800 and 8800 Enterprise to MPP.	Webex Calling. Steps apply to Dedicated Instance.	[cite:4] [cite:6]

What the feature article says it maps

Mapped in the overview	Separate script note	Cite
Auto attendant, devices, configured lines, device layout (speed dial and shared line), virtual line, call queue, hunt group, call park, user calling data (call forwarding and call monitoring)	UserBasedUCMFeatureMigration filters output by a user list, can override location, and creates CallPark.csv and CallPickupgroup.csv because the feature tool does not currently support them.	[cite:3]

Task rules on the user tool

Rule	Value	Cite
Users and devices per task	Maximum 1,000 of each. More than that means another task.	[cite:2]
Task name	At least 8 characters	[cite:2]
Temporary licensing PID	A-FLEX-P-CALL, up to 18 months, opened with GLO	[cite:2]
Phone load before migration	14.1 or later	[cite:2]
Feature tar / Unity zip	350 MB and 2 GB	[cite:3]
Import identity order	If user id, email, and MAC are all filled, the article says it uses UCM email, then user id, then device MAC.	[cite:2]
Cloud-Connected UC	If it is enabled, it takes up the device migration after you complete the task.	[cite:2]

04 · Ecosystem & sister technologies

Glossary, map, sisters, edges

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

Glossary

Migration Insights: The Control Hub assessment that reads a Unified CM tar. Group CSVs show who should migrate together. [cite:2]
A-FLEX-P-CALL: The entitlement PID the user-migration article says you receive when Webex Calling is the cloud deployment option, used for temporary licensing up to 18 months. [cite:2]
Manifest zip: What Complete migration downloads. It contains a CSV of phone MAC addresses to upload on Unified CM. [cite:2]
UserBasedUCMFeatureMigration: The Python script that processes CDR and writes park and pickup files the feature tool does not currently support. [cite:3]
MPP migration: Enterprise firmware to MPP. 8821 and 8831 are not eligible. 8832NR can migrate with limitations. V15 and later hardware needs at least 11.3.3 MPP and cannot downgrade. [cite:4]

Sister-technology matrix

Sister	What it is	Why it matters here	Config touchpoint	Typical failure	Cite
Directory / identity	Webex users must exist before the user tool runs.	The article names Directory Connector or other means.	Provision users first.	A tar of people Control Hub does not know.	[cite:2]
Licensing	A-FLEX-P-CALL and the professional or CX Essentials choice.	Standard is a different path.	GLO for the temporary entitlement. CSV for Standard.	Expecting the task to emit Standard.	[cite:2]
Cloud-Connected UC	Optional device-migration taker.	If enabled, it takes the device migration after the task completes.	Do not also hand-run a conflicting phone load.	Two actors updating the same phone.	[cite:2]
Unity Connection	Optional zip for auto attendant.	2 GB cap. CallHandlerDataDump is the article’s pointer for building the zip.	Feature tool, not the user task.	A zip larger than 2 GB.	[cite:3]
Hunt, queue, park, pickup	Group features the insights CSVs flag.	The implement article says you cannot split them across the local gateway. T6-R07.	Migrate the set together. Park and pickup files may need the script.	A pickup group half-migrated because the feature tool skipped the CSV.	[cite:2] [cite:3]
Firmware	Enterprise to MPP.	8821 and 8831 are ineligible. V15 hardware has a floor of 11.3.3 and no downgrade.	Firmware article. Applies to Dedicated Instance.	Scheduling an 8821 conversion.	[cite:4]
Setup Assist / DI assistant	Cisco-led, and a Dedicated Instance readiness tile.	The DI assistant does not perform the migration.	T5-R06. Do not paste this user-task limit onto that scheduler.	A 1,000-user cap invented for the DI assistant. That cap is the user-task article.	[cite:5] [cite:1]
FedRAMP device check	Optional commercial license check.	The MAC address is sent to the Cisco corporate network if you select it.	The article offers another FedRAMP device process if you do not want that send.	Assuming the MAC stays inside the customer org.	[cite:2]

Cross-platform bridges

This room	Legacy	Peer orientation	Cite
Unified CM tar	BAT export is the input these tools document.	A third-party PBX export is not this tar. T6-R05. TODO-verify a Control Hub tile that ingests Avaya or Genesys.	[cite:2]
Dedicated Instance assistant	Assesses Unified CM for Dedicated Instance. It is not the 1,000-user task.	Do not equate Setup Assist with the self-service user tool. The guide lists them separately.	[cite:1] [cite:5]
BroadWorks migration	T6-R02 cites a separate Control Hub migration. This room does not reuse Unified CM task fields for it.	Read that article before you copy a column name. TODO-verify any field this pass did not re-read there.	[cite:1]

Future-integration hooks

Canon plan: T6-R02 remains the PPDIO narrative. This room is only the tools that article points at.
Canon plan: when the feature tool starts accepting CallPark.csv itself, delete the “does not currently support” sentence only after d2lemv says so. [cite:3]
Phone-load 14.1 and MPP 11.3.3 were retrieved 2026-10-14. Firmware header is May 06, 2026. re-check the user-tool phone-load sentence if that article’s header is older. The retrieved user-tool markdown did not print a header date. [cite:2] [cite:4]

Ecosystem troubleshooting

Symptom	Likely sister-system cause	Check	Fix	Cite
Standard licenses never appear on the task	The user tool cannot assign them.	Call settings radio buttons.	CSV the users, then the feature tool.	[cite:2]
Pickup group is empty after feature migration	The feature tool does not currently support that CSV.	Whether UserBasedUCMFeatureMigration was run on CDR.	Generate CallPickupgroup.csv from the script.	[cite:3]
FedRAMP eligibility sent MACs unexpectedly	The commercial check option sends the MAC to the Cisco corporate network.	Which option was selected.	Use the FedRAMP device process the article names if that send is not wanted.	[cite:2]
An 8832NR lost a feature after MPP	The firmware article says some features may not be supported on 8832NR.	The eligibility table.	Do not treat 8832NR as a full 8832 conversion. 8821 and 8831 do not convert.	[cite:4]

09 · Self-question ladder

Twelve rungs

L0What are the three migration families in the December 2025 guide?

Control Hub tools, certified migration providers, and Webex Setup Assist. [cite:1]

L1Why run Insights before a task?

The group CSVs show shared lines and hunt, queue, park, and pickup relationships that should move together. [cite:2]

L2What is the user-task cap?

1,000 users and 1,000 devices, and a task name of at least 8 characters. [cite:2]

L2Which licenses can that task assign to a user?

Calling professional or CX Essentials. Not Standard. [cite:2]

L3How do you prove the phone job was aimed correctly?

Unified CM target is Phone and the transaction is Update Phone - Custom File. [cite:2]

L3Why would pickup be missing after a successful feature import?

The feature tool does not currently support CallPickupgroup.csv. The Python script creates it. [cite:3]

L4How is this different from the Dedicated Instance assistant?

That assistant assesses and schedules. It does not migrate. These tiles import a tar into multi-tenant Webex Calling, and two of the articles also say their steps apply to Dedicated Instance. [cite:5] [cite:2]

L4Which phones never become MPP in the firmware article?

8821 and 8831. 8832NR can, with limitations. V15 and later need 11.3.3 and cannot downgrade. [cite:4]

L5Why keep the call-park sentences from contradicting each other?

The overview lists call park as mapped. The script section says the tool does not currently support the park and pickup CSVs and that the script creates them. Quote both. [cite:3]

L5What will you not claim about a third-party PBX?

That these tar tools ingest it. That crosswalk is TODO-verify and lives in T6-R05. [cite:2]

L1What does A-FLEX-P-CALL buy you, in that article?

Temporary licensing for up to 18 months while both calling environments are in use. [cite:2]

L2When are both number buttons grey?

When the task mixes premises PSTN locations with cloud or Cisco PSTN locations. [cite:2]

10 · Lab

A paper lab. Do not upload a customer tar to an org you do not administer.

Goal: choose the tile and the license path for four scenarios.
Prereq: x974bd, d2lemv, and n19c71. No live task.
Step 1. 2,400 users. Expected: at least three user tasks.
Step 2. The business requires Webex Standard. Expected: not the user tool.
Step 3. Pickup must survive. Expected: the Python script, not the feature tool alone.
Step 4. The closet has 8821, 8831, and 8832NR. Expected: the first two stay. 8832NR is limited.
Evidence: the BAT target and transaction type, and the two upload caps.
Break it: one task name of “cutover”. Recovery: at least 8 characters, and a second task after 1,000.
Reflection: which call-park sentence you still have to say out loud.

13 · Interview

Oral answers

30 seconds. The December 2025 guide gives you Control Hub tools, certified providers, and Setup Assist. The self-service user task takes a Unified CM tar, 1,000 users and 1,000 devices at a time, and it will not assign a Standard license.

2 minutes. Insights can run in any org and tells you who shares lines and group features. The user task maps device pools to locations, then returns a manifest you load with Update Phone - Custom File. If Cloud-Connected UC is on, it takes the device migration. The feature tool maps queues, hunts, auto attendants, and the rest of its list, with a 350 MB tar and a 2 GB Unity zip. It does not currently emit park and pickup CSVs. The Python script UserBasedUCMFeatureMigration does, from CDR. Quote the overview’s “call park” mapping and that script sentence together.

30 seconds, phones. 8821 and 8831 do not migrate to MPP. 8832NR can, with limitations. V15 and later hardware needs 11.3.3 MPP and cannot downgrade. Those firmware steps also apply to Dedicated Instance.

2 minutes, the other tile. Dedicated Instance has its own pre-migration assistant. It does not perform the migration. Do not paste the 1,000-user cap onto that scheduler. A-FLEX-P-CALL is the temporary entitlement the user-migration article names, for up to 18 months, through GLO. A third-party PBX is not this tar.

What you will not say. You will not say the feature tool builds pickup by itself. You will not put an 8821 on the MPP list. You will not invent an Avaya import button.

Open questions: x974bd and d2lemv header dates. Whether the feature tool has started accepting park and pickup CSVs since this retrieval.
Facts still marked TODO-verify: a Control Hub ingest for Avaya or Genesys; BroadWorks column names this pass did not re-read.
Facts still marked re-check: user-task and feature-tool numbers whose articles did not print a header date.
Assets missing: task screenshot, tool-family SVG export, audio.
Next review: re-check the 1,000 cap and the “does not currently support” pickup sentence together.
