Copy map settings-help

[Bradock]

Hey,
I made a map and modified almost all of the unit properties on it, but I made it too small and I want to make it bigger and change the terrain type.
Is there a way to do that to an existing map?
Alternatively, is there a way to load in all the settings for units/upgrades/special properties from the first map to a new one?
I already know how to load triggers, I just cant figure out the rest of the stuff.
Thanks a bunch.

uhh, there is a way to keep all ur placements+ unit settings, its called use forge, but then again...forge is very glitchy and will not open with any other editor...But open up map properties on Starcraft Forge and itl give you the option to make new settings, itl keep most of ur placement and change terrian. good luck!
