Changing Storage Unit within an NBU Accelerated Policy

Hi,

We have several Netbackup Accelerated Policies that backup to a Netbackup 5230 MSDP pool

Unfortunately, the backup unit on the NBU appliance is too full, so we have to change the policy to use another Storage unit (HP StoreOnce Catalyst) capable of Accelerated backups...

I understand that on VMware the Change Block Tracking map that is in use needs to be regenerated (As it was build up some time ago)

Is forcing an Accelerator Forced Rescan sufficient to get the CBT log regenerated, so that the first backup to the HP Storage gets ALL the blocks instead of just the changed blocks since last backup on the MSDP Storage?

If not, how can this be done best?

Thanks for your help!
