Howto upgrade WPMU with BP running

  • Bento



    It seems im running beta1 of the WPMU 2.7.1 version. I’m ancountering a few errors which should be solvedi in the latest trunk of WPMU.

    How can i safely update without entirely destroying my BP installation? I’m running trunk 1358 (if im correct :P)

    This might be the long version, but

    1. When I needed to upgrade, I backed up my database and copied all the buddypress files into another file called “bosox” (just make up a name). I think you may need to copy your avatars and other stuff into your new install from the old one, so don’t delete the old Buddypress files for awhile!

    2. Then I added the Buddypress files to their new locations and activated it. If you have heavy customization to CSS, you’ll need to re-do the changes (reference your old CSS files).

    3. You’ll also need to:

    – select and activate themes

    – move all your plugins to the new plugin location (it changes in 1.0 from your version)

    – copy avatar files into the new location (I had to do this, but not everyone did)

    Those are the basics. All the best to you!

    As JFcarter suggests, you should make a backup of your database before beginning this process. Your BuddyPress data should be in the same DB as your WPMU data. You also may have some image files in other locations, so back those up as well. Finally, be carful of what you delete in wp-content. If you have any customized themes, or 3rd-party plugins, you will want to make sure you have a backup just in case.

    Now, upgrading WPMU: Unless this issue has been recently fixed, you cannot use the auto update feature to upgrade WPMU 2.7.1-beta1 to the public release version of WPMU 2.7.1. This is because the upgrade script “sees” WPMU 2.7.1 = WPMU 2.7.1, meaning it does not upgrade you from beta1 since it thinks you are already running 2.7.1.

    So, you need to do the old manual upgrade of WPMU following these procedures.

    Upgrading BuddyPress: follow these instructions.
