Don't understand Zones vs. Expansions

[ckempke]

The documentation lists this as "coming soon."

All of my users have Rof2-era clients, but moving around the world it keeps trying to put us in (sometimes non-existent) old zones: east commonlands instead of common lands, tox instead of toxxulia, etc.

If I just set the "currentExpansion" rule in ruleset 1 to "19", will that make it use only the modern maps, or do I have to edit every zone point table manually? (Or something else).

There are all of like three players on the server, so I shouldn't need to support older client builds at all.

(TL;DR: What steps do I need to do to set up "just use the world as it existed for RoF, nothing older.")
