Update/Delete client cache file
Hi - I may need to point a large number of clients to a new Data Domain/dataset and from what I understand, we would need to remove all of the existing cache files on the clients in order for the first full backup/baseline to occur and have the blocks tracked appropriately. If we do not remove the cache file, then references will still exist on the previous Data Domain and block tracking would be mixed up.
Is there a better way of doing this instead of deleting the cache files on the local clients?
Basically... AVCLIENT_1 backs up to AVNODE_1/DD_1. I want AVCLIENT_1 to backup to AVNODE_1/DD_2.
No Events found!

If Second DataDomain is going to be attached to the existing Avamar System then you will have to go through the route of deleting the Cache files for you too perform a Full backup.
If it is going to be a new Avamar+DataDomain system then you can choose the migrate one backup from the existing setup to the new setup.

Would that still be the case if we did DD MTree replication to the new DD then updated the DD in Avamar to use the new FQDN?

If the new DD is completely unused, you can do a collection replication from the current DD to new DD, then do a DNS name swap, where the new DD assumes the name of the old DD.
Avamar creates a unique mtree (using it's System ID) on DD when you first configure a DD as a target. This mtree name must be preserved moving forward.
