PhoneBoy Says

If there's one thing I can take away from this experience, it's that I should really look at having data migrated daily in an automated fashion during the development phase.

Having just went through this myself with the CheckMates Community, it would certainly help but may not truly find out what issues the migration will cause until you rip the band-aid off. It's a month after our migration and I'm still finding small issues here and there.
