I find that I don’t need the advanced features of Devonthink Pro Office or Devonthink Pro. If I buy Devonthink Personal, will it open the databases created in Pro Office?

DEVONthink Personal only supports one database, so at a minimum you would need to first combine your existing databases into one. From there, I believe it would be fairly painless to convert it for DEVONthink Personal use.

I suppose the burning question I have is this-if you have been using DEVONthink Pro (Office) for years now, why would you want to spend more money to downgrade?
