As soon as Byteandahalf finishes his Redstone+ mod I'll have it updated within the day. For now just 12.1 - 3.
Since I'll need to wait for his mod to come out I would say it should be updated less than a month after 13.0 official release. Until that mod I can't update it but it should actually be fine without me needing to do much work at all if any due to design. I try to think ahead when doing my redstone so it will last after an incident last update which caused a map to fail but this design as said should be good to go once the mod is out out since 13 doesn't have all items needed. Just needs repeaters and pistons then it is all set.
Once the mod is out I'll be focusing on my theme park rides again instead of Just houses.
