I had to do it with 10-20 live users and it went fine, nobody noticed anything (I made the change in the night hours just to be sure though). I had to go down and fix some erratic folder names that resulted from the botched separator handling on some macOS Mail accounts.
Did it change anything on Dovecot disk/storage or is the IMAP separator just "virtual" - ephemeral ?
Changing the separator won't fix anything that already exists. You should see nonsense folders in the form of '.folder\2esubfolder‘ there that cannot be worked with in any way. I manually moved the contents of these to their properly named ('.folder.subfolder‘) variants - on disk.
Thanks for the warning Filip!
