At the moment the best method to moving Index Cache is to follow the below documentation:
-Documentation - http://documentation.commvault.com/commvault/v11/article?p=10730.htm
However in your current scenario, as new Jobs are running, it is already requesting the original Index to be Replayed from the references written to the Disk Library.
- Suspend the jobs going to the new MediaAgent.
- Manually move the Index (which you have done)
- Ensure the "Catalog" tab on the MediaAgent is pointing to the new Index Location
- Then start the services and resume the jobs.
This should bypass the need of the Index Recon
Hopefully that helps
