Unrestricted String is Empty – Error in CUCM Installation

Recently i was working on a migration of CUCM from 8.X to 10.X using PCD and i faced an error as “Unrestricted String is Empty” and i had to restart with the installation again and again. I did the installation thrice assuming that the error may wipe out and it will proceed further but no luck. Below is how i resolved the issue.

1. Logged into 8.X Cisco Unified Communication Manager and verified Database Replication which was broken. I fixed the replication issue first.
2. Deleted the OVA and re-deployed the OVA.
3. Deleted the task and discovery information from PCD.
4. Rediscovered 8.X Cluster and created a task again. Started with the migration and it went successful.

Hope this helps!!
