[Borgbackup] Is it possible to encrypt and existing unencrypted borg repository?

Thank you!

Can you clarify the step " use mc to copy from unencrypted mount to new repo"?

I can't find the `mc` command in my terminal (would `cp` work?). Also,
did you mean I mount the old backup somewhere, and ask borg to back up
the mounted files into the new, encrypted repo?

If so, this will probably work to achieve most of my goals, but doing
it this way means the *history* of all of my backups will not be
migrated unless I manually mount each backup in the old repository and
back it up into the new one? Sounds tedious considering I have a lot
of backups in the old repo!
