Disk Groups configured to use the original implementation of AES 256 should be migrated to the current AES 256 v2 implementation. 256-bit AES encryption was introduced in OnBase 14 and renamed to AES 256 v1 in OnBase 14 SP 2.
CAUTION:
OnBase 13 and earlier clients cannot archive or read documents stored in a 256-bit AES encrypted Disk Group. Before configuring AES 256 v2 make sure all clients and the OnBase Application Server are version 14 SP 2 or higher.
