It's usually straightforward. As part of premium onboarding, DonorDock's team handles a white-glove migration, typically in under a week, and a team member reviews your file with you before anything is imported. Contacts and households, gifts with their campaign, appeal, and fund, pledges with balances and schedules, activities, and notes all come across, so your giving history stays intact. Step-by-step guides cover Raiser's Edge, Bloomerang, DonorPerfect, and Little Green Light, among others. For monthly donors, you can ask Stripe to run its own payment migration, and if your current processor releases the data, saved card and bank details come across, so donors don't have to re-enter them.
