I inherited a network that consisted of multiple sub-domains each with their own WP install, and I've begun to migrate to a single install running MultiSite. I'm left with our Buddypress Site and Marketplace. I'd like to keep the same URLs that they have, but running on the MultiSite install and removing the two instances of WP currently running on those subdomains. Can you recommend how I do this?
Currently, I've been thinking that I should create another domain for each, import db data into MS db, and then delete the previous subdomain. Once that's gone I would recreate a subdomain with the same name on MS. The community site, which as a single install with privacy, will then be part of the large MS network and I will use the Membership plugin to control access.
Does this sound reasonable or fraught with danger?
