Pasting a selection from one map into another?

[Psrqx]

This is my first post, so please don't rip me a new one if I'm doing something stupid.

I have three different map files.
1. The big world map
2. A training area I like
3. Sasir's Rook

I'd like to put the training area and rook area into the big map with everything else. I'm using Remere's map editor and I'm not sure what to do.

Also, the rook area is 8.31 (I think) and my server and the training area are 8.54. I assume that the 8.54 map and server will accept anything from previous versions. Is this correct?

Thank you very much!

Just simply update the rookgaard area to 8.54, as well. By going to Map -> Properties (CTRL-P) -> Client Version

Thank you! It works.
