Changes required to each FRX report when moving from 8/Vantage to 9

Can anyone tell me if they have a bullet checklist of action items to perform on each and every FRX report that would exist on Vantage 8 when migrating to Epicor 9?

I understand the license, refresher steps; however I've received conflicting information about what's required in the reports to ensure readiness and testing for them in 9.
Set company - if changing or new
Set COA's - if changing or new
Set Book code in each column definition in each report

Anything else?

Presuming we aren't changing the company or the COA's one would estimate 1 hour per FRX report of work would be required to make it work in 9.

Can you share any additional information?
