Thanks, all your comments are noted.
As I said, you can migrate users individually. You could easily do 10 users a day during coffee breaks etc and be done in a month plus. Do 40 a day and you're done in 10 days. The only time you'll burn is in the learning curve, not the actual mailbox migration which takes no time at all with POP accounts.
That's interesting, as I (wrongly) assumed switching from mbox to maildir was an all or nothing process. You're saying we can run half the mailboxes in mbox format and the other half in maildir format?
In which case we can get going with this sooner than I thought.
Yes, this can be done. But if you're using UNIX system user accounts IIRC you'll have to convert to virtual users before you can migrate one user at a time. Virtual user setup is required to change mail_location on a per user basis. With system users mail_location is defined once for all users. Converting to virtual users first makes the process more painful. I've not done such a POP mbox<>maildir migration myself, so hopefully someone who has will chime in. If not start a new thread called "need POP mbox<>maildir migration help" or similar.
And again, I wouldn't try any of this with 1.0.7. Upgrade to at least 1.2.x first.
Always test with a dummy mailbox first to iron out any issues. Then start migrating the problem users first, the smart phone users who tie up their mailboxes for many minutes during download.
Thank you - I would probably start with the CEO's mailbox first and then go from there >:-D
Start a new thread as I suggested. State your version, current user account type (system or virtual), and post your dovecot -n at the end of the email. You'll get many more helpful suggestions and insight from people who've actually done this migration.
