content conversion – from encrypt to decrypt

We have some content stored in encrypted filestore. We are using Documentum 20.2. Can I decrypt the encrypted files manually and move it to normal filestore? If yes, then how to decrypt the files manually?

By moving it to a non-encrypted filestore, e.g.

fetch,c,<doc-id>
set,c,l,a_storage_type
<non-encrypted-store-name>
save,c,l

Or via MIGRATE_CONTENT administration method.
