RT (request tracker) is behind misc-web but on ununpentium.wikimedia.org
Nowdays it doesn't need a public IP anymore since it does not handle email anymore. We still need it but just as a readonly archive.
Create a new VM with a private IP (eqiad) (and stretch while touching it). Migrate RT to that. Fix issues with stretch. Adjust the misc-web director to the private IP.
Once done remove the old jessie VM and kill it from .wikimedia.org DNS zone.
