This show can be a little complicated due to how TVDB and TMDB order the episodes. I ended up naming my files using TMDB ordering and their strict aired ordering rules which also splits the shows into four different categories…
Battlestar Galactica (1978) {tmdb-501}
Galactica 1980 (1980) {tmdb-4621}
Battlestar Galactica (2003) {tmdb-71365}
Battlestar Galactica (2004) {tmdb-1972}
… which includes the miniseries from 2003. If you want I can provide a text file with the naming I used for reference.
