UCCX Replication bug

Don't you love when you spend a LOT of time troubleshooting a problem just to realize it is a bug ¬¬ 
Well, that happened to me a few months ago with not least than the database replication on Cisco Unified Contact Center Express (UCCX) v11.5.1.11001-34

Since it is a major problem, you will see it in multiple places, two examples below:

Under replication status:
You can also see this running the command "utils uccx dbreplication status"

While attempting a backup: 

This is related with BugID: CSCvd81014, we spoke with TAC and the fix procedure was the following

  • Go to Cisco Unified CCX Serviceability 
    • Tools > Datastore Control Center > Replication Servers
    • Disable CDS/HDS Datastore  
    •  <<<Wait 5mins>> 
    • Enable CDS/HDS Datastore  
  • On the CLI run the command 
    • utils uccx reset replication all
    • utils service stop Cisco DRF Local
    • utils service stop Cisco DRF Master 
    • <<<Wait 5mins>>
    • utils service start Cisco DRF Local
    • utils service start Cisco DRF Master
  •  Restart CCX database on both node
    • utils service restart Cisco Unified CCX Database

After that the problem solved, backups were successful and it has not been recurrent since then.
I really hope may save you so time.
