I would like to move 400 skins that I have changed in RTW 1.2 to RTW 1.3 all I have down in 1.2 is
CVP
Darthmod's pack
linedogs map

I have downloaded skins from virtually every source imaginable from TWC to change the skins in my version.

I would like to move the skins over to 1.3 without redoing the whole process. Does anyone have any suggestions.
What things do I have to look out for etc?

The other things I can move over or redownload later I am interested in saving all the time put in making new units with skins etc. I really dont want to start from scratch.
