I'm just wondering, if I do a wordpress upgrade in my wordpress installation, do I have to run the upgrade script (in order to effect any database structure changes) in each blog under the hive?
Also, what about plugins upgrades? A good practice is to deactivate plugins first before upgrade (as what the automatic upgrades does starting with WP2.5). If I use the same plugin in various blogs within the same hive, and I upgrade a certain plugin from a particular blog, I think it does not necessarily deactivate the plugin first from the other blogs. How do we address this issue?
