I have a Pegasus2 R4 configured as RAID5 with Mac OS Extended (Journaled). The drive has a lot of files and is almost full.

I would like to encrypt the full logical drive by converting to APFS (Encrypted).

What will happen if I right click on the drive in Finder and chose "Encrypt..."?

Will this convert my RAID5 Logical Drive to APFS (Encrypted) without any problems?

Will Promise Utitily still work normally?

What else should I be aware of?
