I have a WordPress "mapped domains on a subdomain multisite" on WordPress 3.0.4 and want to upgrade to 3.1.2
I use WordPress MU domain mapping plugin 0.5.2.
I have some questions on the upgrade.
I was thinking about doing the upgrade as follow:
2. update plugins and themes
3. update WordPress MU domain mapping plugin
4. Auto upgrade WordPress (I want to auto upgrade as I have several plugins and multiple websites which don't use the same plugins)
My questions are:
a. I read warnings about the automatical upgrade. But according to this post "the problem seems to be caused by a messy previous upgrade in which files are left in a temporary “upgrade” directory with the wp-content directory. In order to solve the problem, you simply need to delete the “upgrade” directory in it’s entirety and then try the upgrade again." Will this work with upgrading WordPress multisite too? I'm I safe to upgrade WordPress Multisite automatically?
b. I currently have the domain_mapping.php plugin placed in mu-plugins folder and sunrise.php in wp-content. According to the WordPress MU domain mapping plugin instructions I shouldn't place domain_mapping.php in mu-plugins. What is wise to do? Can I just try the new version on the plugin in the normal plugins folder? If it not works I just place it back in the mu-plugins folder?
