I am attempting to add a new subscriber to CUCM 12.5.1.10000-22 server that I just finished upgrading from 11.5, but I get the following message after I try to add a new server:
Add failed. Upgrade and migration for Cisco Unified IM & Presence Servers associated with this cluster appears to be pending (not complete). Please make sure upgrade and migration of all IM & Presence servers is completed successfully before adding servers to this cluster. Please check for any unused IM & Presence Application Servers and delete them.
I do not have an IM & P server and never have, I also checked to make sure I wasn't crazy and there is only a single node shown in the CLI:
admin:utils dbreplication runtimestate
Runtime state cannot be performed on a cluster with a single active node; aborting operation
