Upgrading from a very old version of mu, best practice? (6 posts)

    Hey Gang, I have taken over a mu-workpress site that hasn't been updated in years. It's for a non-profit and has about 70 active sites on it.

    It's running 2.3.1 which I believe is really mu version 1.3.1

    How should I go about upgrading, should I do it in steps, ie go to each major version first? or can I safely jump to 3.2.1?

    I do know that several of the plugins currently used are not actively being developed, but we should be able to get around those, and find replacements. The only document I have been able to find is this.

    http://codex.wordpress.org/Upgrading_WPMU

    But it doesn't address anything after version 3.0.X

    Ideally I would like to take a backup of the site and do test upgrades, but my first attempt at modifying the db for the test URL hasn't worked. But I'm still looking and reading.

    Thanks
    Damon

    Steps.

    ALWAYS steps.

    Once you get to 3.0, you're actually going to be on regular WordPress. Which means you should THEN upgrade (manually) to 3.1 and FINALLY auto-upgrade to 3.2.1

    This is not going to be fun :)

    How does this upgrade path sound.

    Currently 1.3.1
    to 1.5.1
    to 2.6.5
    to 2.7.1
    to 2.8.6
    to 2.9.2
    and then to 3.0?

    I would assume that the latest major version is the best route to go?

    Thanks for the links.

    I would do 3.0 to 3.1 to 3.2.1 personally, hitting up every major.

    yep. and then to 3.1 and 3.2.1 .

    It;s laborious but makes certain the db gets the needed changes.
