The folks at PluginBuddy have released an add-on to their WordPress backup plugin BackupBuddy called BackupBuddy Multisite. The new addition to BackupBuddy will allow for migrations from a standalone WordPress site over to an established Multisite installation.
As PluginBuddy’s Ronald Huereca explained, a normal export and import into a Multisite installation won’t bring with it active plugins, theme settings and widgets, necessitating a special tool for an easy site migration.
Check out the video demo of the new add-on just after the jump.
The plugin will currently only help you bring a standalone single WordPress installation into a network, and not the other way around. Huereca explained in the comments of their post why it’s currently a one way process:
I’ve seen the use-case of someone wanting to put a site into a network, but never the opposite. If you have a network of 1000 sites, you wouldn’t ideally want to develop a site on that network, you would want to do it somewhere else.
As far as the reverse, pulling a site out of the network… Keep in mind that a single site in a network is not a full WordPress install. It’s only several database tables and shares the themes/plugins/global settings with the network of sites.
Pulling this individual site out of a network and piece-mailing a WordPress installation out of it (along with appropriate wp-config and htaccess rules) would be a tremendous undertaking that we’re not prepared to take at this time.
Have you given the BackupBuddy Multisite beta a try yet? What method do you use when you move a site from a standalone into a Multisite network?
