Currently we have a site that uses versions 1.x and 2.x. There were too many breaking changes between versions 1 and 2 for us to convert all of our pages, so we recompiled one of the versions with a new namespace so that 1 and 2 could live in the same website.

Now we are looking into version 4.1 and wondered if we could do the same thing by recompiling and namespacing version 4 (or 1). If the upgrade from version 2 to 4 has no breaking changes then we could do away with version 2 but we still need to support version 1 on the same site as version 4.

Is this a possibility? It appears the source is not available like it was in the past.

Thanks for you time,
Robb
