    Question Downgrade from 5.0 beta to 4.5.x?

    Guys,

    I loaded 5.0 beta last night, and while it looks promising, I wondering how I can downgrade to 4.5.x without losing any emails. Is it the same process as upgrading?

    Thanks,
    jbwiv

    no! upgrade process upgrades db schemas, this won't work in reverse. to downgrade you have to restore from backup.

    Oh yeah...suspected as much, but had to see for myself yesterday. Didn't go well

    Ever have one of those days where you're just in the mood to upgrade, and forget to ask a few very important questions?

    Hello,

    i have a similar problem. Had a temporary testing version on a testing server with 5.0 RC1 installed. Now, i need to put the server in production, but would like to downgrade to 4.5.9 for now, until 5.0 is final. I don't have much stuff, one domain, a few COS's defined and some 20-30 email accounts, empty for now, but all set up waiting to go live. I am using external LDAP authentication.

    What i would like to know is, what all i must backup in order to preserve 'same' configuration, with domains and accounts and COS, ok COS i can define yet again, not that complicated, but accounts i'd like to keep.

    Is ldap enough? There are 3 ldap folders, i will just backup them all. What about mysql, does that need backuping too?

    Thanks for info.

    Your best option would be to set-up another server and copy the data across with IMAPSYNC - do not attempt to downgrade from RC1 to 4.5.x

    Ah yes, thanks, downgrade is out of the question.

    I had a clean reinstall in mind with OS included.

    Think was a bit unclear, my accounts are empty, no messages in them yet, and isn't IMAPSYNC a tool just for that? Migrating mail? I just need accounts to be created, with settings, not the emails, the same way they are now.

    I assumed you had email on the server, if that's not the case I'd just go for the clean install. You could dump a list of users with zmprov but if it's only 20-30 then it's not going to be too long winded setting them up again.
