#zone sro <-- old version
#zone southro <-- revamped version
In your zone_points table and doors table, pay close attention to the client_version_mask field, as it will determine which version you get based on client when attempting to zone through a zone point or door. Likewise your spells may have client version comparisons to determine destination zones.
