I am fairly new to the game, so i have no clued about the edition 1.0 vs 2.0 etc.

I own two copies of the old core game (2012) and found a good deal for the squadron starter (rebellion and imperial) and just found out that they use different rules, cards and materials.

Are they still compatible or do i need to upgrade the old sets?
