You only data transfer it to your 3.55 PS3 for "backup" purposes. Then you data transfer your "backups" to your 3.70 PS3 and play it there. That way you won't have to go re-downloading it. Also, you don't have to worry about "Activation/Deactivation". If you are using the same PS3 then PSN allows 5 activations per week per console. (Assuming that it is the SAME PS3 CONSOLE that is being reactivated.) I should know, because I do it all the time for my MW2 patch/Map Packs, ALL MY PSN STORE DLC/GAMES, BO Map Packs, etc.
I hope that made sense. If your stuff is from game sharing then you're on your own. All of my DLC are bought by me so it works...
