Same-server mail transfer

Hello,

What would be the best way to perform a same-server Maildir transfer, while retaining the IMAP structure already in place, between users with the same GID but different UIDs?

I've tried doveadm import but I presume it is encountering a permissions error due to the different UIDs.

Worst case scenario, I could move everything over manually and then update the UIDs. I feel like there should be a more elegant solution though that I'm not immediately grasping however.
