old Bookpedia 2.0 database- delete?

[ProWorks2]

I have used Bookpedia since version 2.0, and after many upgrades I finally noticed that my Application Support folder has two Bookpedia entries. One is titled "Bookpedia" (the current database) and one is titled "Previous 2.0 Bookpedia". If all my entries have been updated to be in the latest version, do I need to keep the "Previous" folder (is there an advantage to keeping it?), or can it be deleted?

It was a precaution during the upgrade process, feel free to delete the older folder.

Thank you for the quick reply - didn't know for sure that new database included the old.
