[resolved] upgrading MU from 2.82 to 3.0.1 using MU in a subdirectory (21 posts)

    Hello,

    I tried and failed to use the automatic upgrade. The error was that my installation could not be found. I'm wondering if this is because I'm only using WP MU for a portion of my site. Not the home page of my site, etc, etc.

    I am trying to do it manually for now.

  2. No, it's because you're upgrading from 2.82.

    Upgrade to WPMU 2.9 and THEN to WordPress 3.0.1

    What I did was to follow the manual install option using the instructions here: here

    So the site appears to be updated, but when I browse to a site it appears to be blank.

    The files and data still exist. I can see them in the backend. But I cannot see the live site.

    Does this ring a bell?

    I have my backups and can start from scratch if need be. Should I start over?

    Thanks.

  4. The trick, when you're upgrading from more than a major revision out, is to do it in steps.

    I would download this http://wordpress.org/wordpress-mu-2.9.2.zip and try uploading those files to your site. See if that works. If so, THEN you can try the automatic upgrade. If not, restore from backup and go here http://wordpress.org/download/release-archive/

    At the bottom you'll see all the old MU installs. I would basically hit them in this order:
    2.8.2
    2.8.5
    2.9.2
    3.0.1

    OK. Thanks. I will try 2.9.2.

    A question. Should I re-delete everything in wp-admin and wp-includes, etc. first, the way I did before? Or can I just write the successive upgrades over each time without having to delete in between?

    Thanks.

    Normally it's safe to just overwrite, but in this case, I would say to delete wp-admin and wp-includes before you upload the 2.9.2 files :)

    Thank you so much for your help. I will roll up my sleeves and step back through all of the upgrades.

    Thanks again. I really appreciate it.

  8. How about the actually Upgrading WPMU instructions?

  9. Oooh! I didn't know we had that!

  10. :D Says what you told him to do anyway, just in a handy list. ;P

    what you told her to do... :)

    now do the Upgrading WPMU instructions still apply given that MU is no longer being developed?

    Thanks,

    Audg

  12. Yeah, because you're still on MU and you have to get your MU install to the point that it's able to be flipped over to MultiSite :)

    Alright...maybe this girl is not so powerful after all.

    I restored my database and files from my backup and the site was working fine again.

    Then, I copied over all of the files from the 2.8.2 install (except the wp-content folder, and wpconfig.php) as per ipstenu's suggestion.

    Now when I try to log in to the admin folder or view a blog on my site it brings me to wp-admin/install.php and is asking for my username, etc.

    I'm afraid that doing this will wipe out all of my database tables and files.

    Any guidance would be very much appreciated!

  14. It won't overwrite, but the generic 'Make a backup of your database before you start!' rule applies.

    Your wp-config.php file is pointing to the right database?

    I do have my orig db and files backed up.

    My wp-config is the original one, and pointing to the original db.

    Is the install going to modify the databases? Is there a list of things the install does?

    Thank you for your help!

    alright. I braved the install.php file and now it looks like my database content was essentially wiped out. I.e. the only two entries in wp_posts are the default 'welcome' posts.

    It seems like there has got to be an easier way to upgrade to MU 3 without losing my data?

    I know...I should have been upgrading all along....and now I wouldn't be in this mess.

    But at this point...not sure what to do next.

    I guess I'll try to restore my original database and see what happens.

  17. It will not wipe out your db and files.

    alright...sorry to be a bother. Maybe I will start from scratch again and see if I can get better results.

    Not that you need the gory details, but at least one of the things I did wrong was to install the regular wp and not the MU version from the release-archive!

    Hopefully that explains what went wrong and it will all be smooth sailing from here!

    Thank goodness for backups!!!!

    ;)

  21. There is no difference, as of WordPress 3.0, between the installers for MU and regular, by the way :) But yeah, pulling the 2.8.2 regular would have done that!

    Glad it's all good!
