oilbased over waterbased

Boy am I glad I signed up to these forums...so many questions!
So the old trim paintwork is waterbased and I want to use an oilbased paint. What would you guys suggest I do to prepare the old trim for the new paint inorder to avoid any unwanted seperation or something similar? (By the way I decided to go the paintbrush route).

oil over water is okay. you shouldn't have any problems. it wouldn't hurt to lightly scuff-sand first though.

the problem is putting water-based over oil. then it doesn't stick.

Definitely scuff it up before you do anything else for adhesion and you might want to vacuum or dust off whatever you're painting to reduce grit. That will make the wood work a lot smoother. One helpful thing is to try and get as much of the prep work done before your first coat of paint (if you're doing two coats).
