Do you need to connect to 2 different databases simultanesly on develop server
and 2 different dbs on production server at the same time?[/quote]

LOL ... it IS confusing

We manage 63 student apartment properties and they each have a website. There is a single CMS that governs all of the sites. There is a development site for each property (where the property personnel can "test" their updates) and a production site which is open to the public.

The CMS has to be able to read and write to both databases.
