    Will there be any problems, breakage if MySQL is updated from 4.0.x to 4.1.x?

    Hopefully not....I have upgraded my servers with Mysql 4.1 from MySQL 4.0 but didn't experience any issue while upgradation. However you must note that the change is not reverseable so you should take the backup of the databases if you want to get back to MySQL 4.0 again.

    How can I go back to 4.0?

    I had an employee do the update thinking he was trying to help and now I have broken websites...

    Thanks!

    Were all databases backed up before doing so?

    Furthermore, what was the exact process that was followed? Merely upgrading from 4.0 to 4.1 will break MySQL-dependent PHP-based websites. After upgrading MySQL, you'll need to rebuild Apache and PHP.

    i upgraded from mysql 4.0 to 4.1 - no issues. mysql 4.1 to mysql 5.0 no issues. no sites broken. i stick with mysql 4.4.2 though cuz i have my helpdesk broken if i go for 5.1.4.

    after upgrading the sql you need to recompile apache and php. otherwise will be broken.

    There are no problems after upgrding mysql from 4.0 to 4.1.

    You will gave to recmplie apache after upgrade. You cannot downgrade to 4.0 after upgradation.

    Go on, have a guess
    Well, there certainly can be, it wouldn't be accurate at all to say that there are no problems as evidenced from the many posts on these forums.

    It's not really a problem to upgrade..just remember to rebuild Apache/PHP once you are done via /scripts/easyapache.
