Hi Christian,
All the scenarios involving simple migration ( keeping same ip address and hostname ) and network migration ( changing ip addr or hostname ) for secure and non secure clusters are covered under "Run a Migration Task" section of the following link

8.x, 9.x, and 10.x | Network migration | Secure | When the migration task reaches the Forced Paused step, perform the following steps: - CTL Update
- Bulk Certificate Management
- Resume the task on Cisco Prime Collaboration Deployment GUI.

Postmigration Tasks for Cisco Unified Communication Manager Nodes in the Cluster
"After the migration task runs successfully, if a migration task with network migration was performed, some additional steps are required. (No postmigration tasks are required if a simple migration was performed.) "
Consult the following table and the applicable migration Use Case flowchart to determine whether any user tasks must be performed after the migration task is successful.
