We are migrating 3 individual WordPress sites into a Multisite installation. The 3 sites are currently live at site1.example.com, site2.example.com and site3.example.com. I have installed WordPress Multisite at wordpress.example.com using subdirectories, that is we have wordpress.example.com/site1/ and wordpress.example.com/site2/ and wordpress.example.com/site3/
With the Domain Mapping plugin, is it possible to map the subdomains to these new subdirectories? site1.example.com -> wordpress.example.com/site1/
Or will this not work?
