What Craig says.
Usual joke is that there are two types of migration projects: those that plan to move a lot and then give up at go-live time and only move a little, and those that plan to move a little.
I’d always recommend moving the minimum and keeping everything live on a stripped-down version of the old database, with individual and aggregate queries, and, if you pay that way, very few licensed users.
