Three major points, first;
1) The RaceConfig.xml file has a number of tags which must be edited.
2) Tech Tree(s) & PlanetImprovements xml files have to be "adapted" for proper readouts of the above, too.
3) There are also other files which must be "converted", but that has to do with how extensive that specific mod is.
Soooo, generally speaking, one could simply compare some files from DA & TA and figure out (quite easily, in fact) where obvious differences occur.
X-Worlds #06-A was made partially compatible with TA, if you follow the instructions given you'll be transfering a Race mod (i have to presume Graphics & RC file only in your case, btw) in no time.
