We want to convert the Mediawiki maintenance servers to stretch. ( T192092 )
We can't just take down terbium and upgrade it in place.
So per Service Operations meeting we need to spin up a replacement maintenance server using stretch and have it running in parallel for a while to replace terbium and ultimately decom terbium.
Checking racktables i see there is an unassigned server in the same rack, right above terbium, WMF 3565.

They are both Dell PowerEdge R420 and have the same purchase date. (Though, one of them says they are out of warranty and the other doesn't. )(?)
Requesting to assign WMF3565 as the terbium replacement.
