"Does QB have a wizzard that will walk me thru what needs to be repopulated once I do this condensing back to like 2014?"

 

Run your reports and keep them for reference. Make a backup of the current file and keep it for reference.

 

After you do any housekeeping, rerun reports to see what is changed. That is what you would need to Repopulate, in the case of Deleting. The Condense function isn't quite that bad, but there is a lot of housekeeping to be done, to make that work well.
