questions for DDB signature and re-baseline

Hello Community

#1  vms are linked to the same storage pool and DDB is enabled, when moving the VM between subclients will initiate a re-baseline ?
 
#2 Could you confirm whether Commvault generates the DDB signature based on the server name or UUID or else?"

#3 If we enable Commvault encryption on the subclient level, will this trigger DDB re-baseline when the scheduled job starts for the existing subclients ? if so, does job will convert to full automatically or has to run full manually ?

thank you
