Before you create a new encryption DB policy, use the PROUTIL EPOLICY VIEW utility to check the states of existing policies and encrypted objects.

For example: 
PROUTIL sports2020 -C epolicy view dbpolicy
Encryption DB policy: CURRENT  V:4 AES_CBC_256 
Encryption DB policy: PREVIOUS V:3 AES128_CBC_PBE

The command found two policies: current and previous. Whenever there are two policies displayed, you need to run EPOLICY VIEW TABLE/INDEX/LOB/AREA/ALL to find out whether there are object policies that needs to be updated. Run an update command to make sure that objects encrypted with the previous policy are all updated to the current policy.

For full syntax, see PROUTIL EPOLICY VIEW qualifier.

You may use PROUTIL EPOLICY SCAN to find out how many blocks use the previous policy. Keep in mind that PROUTIL EPOLICY SCAN takes longer, because it is not a read-only operation.
