    The coexistence will be established between two separate data centers to migrate users mailboxes

    I want to double confirm with you that those two data centers are separated or coexist in one organization?

    If they coexist in one organization:

    About MX record:

    You could point MX record to any of them (New or old data center), you could also confirm with your DNS supplier, whether they could provide DNS points to two datacenters.

    About Edge server:

    You could create a new Edge server in the new datacenter, then follow this article to create Edge Subscriptions with Exchange server in new data center.

    About migration:

    You could migrate them from old data center database to new data center database directly.

    If they are two separated organizations, you will need to migrate data with export/import PST. After migration, switch MX record from old one to new one.
