That's not much to go on. You haven't provided ANY indication of what kind of data volume you're dealing with, nor any indication of what kind of environment this is beyond the labeling of it as "production", nor any information on where the data is coming from, and yet you want a strategy for dealing with it? Seriously? We may have expertise, but we're not genie's capable of magically understanding what you are up against. You'll need to get into a LOT more detail before anyone can give you much more than the equivalent of BE CAREFUL and TEST your migration process on a non-production system to validate that it works.
