So this is all interesting from a technical point of view but from a business point of view it makes no sense. The amount of time that you had a talented DB dev working on a project that could have been solved by spending ~25K on a new system seems silly. Bring the new system up and move the data over the network doing the conversion as part of the move. 100TB over a 10G network is ~22H theoretical transfer rate.
