Currently there are two namespaces in use, Aurorawiki and Examples (I think). Aurorawiki is where all of the pages are that we are concerned with. Examples contains all of the ship examples that were put up ages ago.
The versioning uses 5.50, 6.00, 6.40 and Current_Version. There are namespaces created for those. So pages need to be moved into the namespaces for the appropriate version.
So let's assume the next two versions are 6.50 and 7.0. When 6.50 comes out, everything in Current_Version gets moved into 6.40. When 7.0 comes out, a new namespace of 6.50 is created and all Current_Version moves into that namespace leaving Current_Version for 7.0.
Minor versions such as 6.43 or 6.42 live in Current_Version with the exception of something in 6.43 overriding something in 6.42.
