Most of them are very easy to move. A few, mostly the big complicated ones like Pirates of Drinax, are challenging to move. But all the short adventures are easy to move with a few name changes and maybe sticking secondary world in a system if you don't want to adapt too much. Some nasty hellplanet or space station can be in literally any system. More specific world set ups might be trickier, but remember that many systems have distant companion stars that can have their own habitable zone if you need a place to stick a planet, especially a little visited one.
And you can just plain swap a planet if you want. I really liked how Bellerophon from Nomads of the World Ocean was and I had a water world (Sansterre) in my chosen region. So I just transplanted all the stuff I liked from Bellerophon to Sansterre. Done.
