The platforms differ. The mistakes repeat.
People map skills to queues and also to proficiencies and double-route. They forget that a PSTN transfer drops attributes, so the CUCM agent has no screen pop. They compare AHT that includes ACW with AHT that does not. They port the number before UDP 3478 is open. They discover campaign or outbound country limits on week one.
Webex Contact Center is a competing CCaaS, not a card you slot into Connect. Genesys Edges and Avaya port networks do not become Connect constructs. You replace them or you transfer to them.
- Write the AHT formula on the report.
- Test the external transfer with a real desk phone.
- Inventory holidays.
- Decide what 'abandoned' means.

Glossary
- Calling search space CUCM's list of partitions a phone may dial. The Connect cousin is a routing profile, and they do not configure each other.
- CSQ A UCCX contact service queue. Map it to a Connect queue, not to a routing profile.
- Precision queue A UCCE queue with attribute steps. Map the steps to routing criteria, not to one flat skill group.
- Finesse The Cisco agent desktop. The Connect cousins are the CCP, the agent workspace, and a Streams application.

Sister technologies
Migrations fail when a skill group, a script, and a Finesse gadget are all called 'the queue'.
Config and troubleshooting
A spreadsheet that says 'like for like' with no formulas.
CUCM, UCCX, and UCCE have no CloudFormation resource in this API. The objects you create on the Connect side are the queue, the routing profile, and the hours. Map the old skill group onto those, not onto a single queue name.

Cross-platform bridges
A CUCM calling search space is not a routing profile, but the profile is the closest idea of 'who can receive what'. A partition is not a Connect object. A UCCX CSQ and a UCCE skill group map to a queue. Precision steps map to routing criteria. A script, an Architect flow, and an Avaya vector map to a contact flow.

Future hooks
Hooks you can adopt later: EventBridge contact events, the CTR stream, agent events, Kinesis Video, Customer Profiles events, Cases, Show view, data tables, External Tool, and the flow language JSON in your pipeline. Live Sync and Agentic CX are the 2026 hooks for guided and agentic experiences.
