Migrating MPLS phased approach?

Just looking for quick and high-level suggestions/advice, I can do the leg work of figuring things out from there.

Helping out a friend with migrating MPLS providers, while keeping the network functional as there are multiple branch locations that will be cut over individually.

What is the (I guess) easy/cleanest way to get this done? We plan to do the data center leg first where all of the branches come to for services while migrating the sites we will keep both MPLS links connected for new and old. BGP is connecting the MPLS network, redistributing EIGRP from the internal side.

Attached is the most basic high-level diagram, If more info is needed I can provide

Is it just a matter of configuring a separate BGP process for the new Provider and redistributing EIGRP to it, and the routing table will handle having both MPLS networks in its table and route traffic accordingly?

Just seeking advice for the "easy" way to do this. Thanks guys
