Getting rid of iPad, anything needed for sync store?

I got a new iPad and have set it up syncing to my Dropbox sync store. The old iPad is going to be erased and given away. Is there anything I should do in order that no “cruft” is leftover in the sync store relating to the old iPad and it’s syncing to it?

Deinstalling DEVONthink To Go on the old iPad is sufficient.
