Moving information between Databases?

Hi - new user here…

Just wondering what the best way to move items between databases would be. I work on a lot of recurring annual projects and it would be great if I could keep one database with information on projects that are far off - then move them into their own database as they become more active. Would I just drag folders to the Finder - then drag them again to a new database window?




Really loving this program - been looking for something like this for awhile.
