Just to share some operational experience, I set MTU=9000 on all our networks including the migration network 👍
Worthy mention: You must ensure this is applied on network equipment otherwise your packets will fragment which would likely result in worse performance than leaving the default MTU of 1500.

They should have IPs yes, but without a GW set.
I think It is better to have isolated vlans, the whole point of separating the 2 networks is generally for this purpose, only data traffic traversing.
I am really tempted to try jumbo frames as well although the network I am under @ work is not one I can risk playing with at the moment.
