In your case, assuming A is the directory of your old world (the one where you want to change IDs), and B is the directory of the new one, you would just have to do something like:

cd A/DIM100/region java -jar RegionScanner-1.03.jar --from A/level.dat --to B/level.dat *.mca Then you would either copy some of the resulting region files in B, or copy B's level.dat file in A and make some schematics.
