A few days ago I upgraded my WordPress MU installation. It all went smoothly with no problems at all. Thank you guys at WordPress for doing such a great software.
I’m hosting my site at Lunarpages and since it is a shared server you can’t use ssh, so I had to use FTP and cPanel when upgrading.
Ok, this is how I upgraded wpmu from 1.2.5 to 1.3.
- I know that this step isn’t always my first choice but I thought that I would try it anyway, RTFM.
Read the upgrade guide at WordPress and the extended version to.
- Make a backup of the installation, the wpmu folder (public_html/blogs) and the database (wpmu).
- I decided to upgrade a copy of my wordpress installation folder so I could easily switch to that when it was time.
Copy the blogs folder to wpmu13
- Download the tar file from WordPress MU
and save it on your desktop or server (in my case it was the desktop).
- Extract the tar file.
- Ok this was the part when I had to focus. According to the upgrade guide I should delete the old WordPress files but DO NOT DELETE everything. Since I’m upgrading a copy of the WordPress folder I wasn’t so nervous. I used a ftp klient when deleting them, just select everything and then unselect those files that shouldn’t be deleted. And yes, it is in the wpmu13 folder I’m deleting files
- Now upload the WordPress MU folder that you have download and extracted in the previous step. If files already exists, just replace them. Don’t worry, remember this is just a copy of the original folder. Yes, it’s still the wpmu13 folder.
- Now it’s time to do the real upgrade step. Make sure no one is using the blog, then rename the original blogs folder to wpmu125
- Rename the upgraded folder from wpmu13 to blogs.
- Point your browser to http://<your-domain>/wp-admin/upgrade.php to start the upgrade of the database.
