Programs will have to be installed on the new computer.

Go into Sonar and look at the folder locations in Preferences - then go look for any custom ones you may have created.  The data/time stamps will help you see those.  Templates

Same goes for any custom drum kits or synth settings/presets.

Also, take a spin through the Preferences settings and make note of any you have tweaked.

I think that sort of approach would do it, of course leaving things on the old system until you are satisfied all is OK makes sense too.  Presumably there would be an additional layer of protection in any backups you made on the old system.
