Question Update or migrate first?

[Nathan]

We have 2 Plesk servers running on Windows. One is version 12.0.18 Update #103, and the other is version 10.3.1. We're going to decommission the version 10 server but first have to migrate 5 domains off of it. Should we first update the version 12 server to 17.8 and then migrate the domains over? Or first migrate the domains and then do the update?
