Hello!
I am experiencing issues from migration Call Manager 8.6 to Call Manager 12.5 (and 10.5 to 12.5, and 11.0 to 12.5) using PCD 12.5

- bootable CUCM Software (Bootable_UCSInstall_UCOS_UNRST_12.5.1.11900-146.sgn.iso) ;
- PCD (PCD_UCOS_12.5.1.10000-18.sgn.iso);

Hi,

The error is very generic and caused due to DB issues, so collect the install dump and open a TAC case for detail assistance.

support has not yet been bought :))

it turns out the databases are different on different versions UCM? 11.X from 12.5

follow :

https://community.cisco.com/t5/collaboration-voice-and-video/dumping-cucm-fresh-install-logs-virtualization/ta-p/3148966

to collect the install dump, and past it hear, if not complex will help you out else TAC is the best place for it.

difference in DB depend after checking the logs, as said the error you get it generic for many thing that might have encountered during installation. also check the server state if read/write policy is good and there are are no deadlock of resources and installing database is a accessing physical disk as well for writing the db component.

Сan migrate immediately from version 11 to 12.5, or need to migrate to 11.5, then to 12.0 and then to 12.5 ?
