I currently DM In a family game and would like to move some of the characters i created for that campaign into a new campaign I’m creating.  Is it possible to do so without re-entering all of the information?

Make copies of the characters. Send out campaign invite link. Join with copied character. That’s only way I can think of if I’m understanding you right.

Thanks.  

You only need to make copies if you want them in both campaigns. But they will be different characters and not have anything to do with each other from that point onward. If you just want to directly transplant them it is the same method, but no need to copy the characters first.
