I suggest you run the new and old version of Manger side by side with the same data file. You will then be able to drill down on values which are different to see why. With specific information, other members of the forum are likely to be able to describe efficient solutions.
To run two versions of Manager you need
- Two computers or at least two logins
- a back up of your business from before you upgraded Manager
- A copy of the old Manager program or at least a computer running the old version of Manager. Provided your old version of Manager was not too old you can get a copy of your old version of Manager from Restoring data issue - #2 by Patch
When you have these components
- install the old and new version of Manager on different computers / computer user login accounts
- Import the same old business data file into both versions of Manager
- Drill down on numbers which as different to see why
- Ask on the forum for the easiest way to fix the differences you find
