checkboxes & fmp 6 to 8 advanced

[registrationgal]

I currently integrated several small databases in fmp 6 to one large database that contains several checkboxes. My boss bought fmp 8 advanced and I would like up upgrade but I fear that i will have to go through all 3,000 + files and re-enter the data in the checkboxes by hand, as i did when i integrated the database the first time. Will this happen? Or am I safe to upgrade with no worries?
