When converting from Paradox to SQLite, I ran into 2 problems.
1) the TableName.DB I used in paradox does NOT have a .DB ending in the actual tablename...
2) The data module where the "database1" was declared for the TUniConnection was not included in the files, and then the connections were not set to them. I had to open all the forms and remove the .db and set them

I think that the Migration Wizard should handle those better...
