Import collections from previous database

I attempted to upgrade my metabase install and it seemed to get corrupted. I did not have a backup. After a while i did a fresh install of metabase to an sql database. My question, Is there any way to import data from a previous metabase installations sql database into a new installs sql database? I want to import reports or collections that i had saved in my previous install of metabase, and users would also be nice. Prior install and current were connected to the same ibm database. Nothing has changed so im assuming this is possible?

If so would someone know what tables? Or some type of procedure to do this?

Thanks.
