The host is ready to be decommissioned.
What I have done:
Removed it from prometheus, added it as a spare on site.pp and removed it from dhcp list: https://gerrit.wikimedia.org/r/#/c/351813
Removed it from php config files: https://gerrit.wikimedia.org/r/#/c/351814/
Removed it from the software repo: https://gerrit.wikimedia.org/r/#/c/351815/
MySQL is stopped.
@Cmjohnson the host is all yours now.
Thanks!

This is probably not fully decomissioned yet (dns, puppet, etc.), but I am going to try to remove it from puppet and icinga so it doesn't create garbage on alerts.

Actually, I cannot do all the steps (network changes) without coordinating with DC ops. I do not have any blocker on this getting fully decommed soon, but I would like to remove it from icinga. Let me know if removing it from puppet and icinga only (db1022 and db1023) sounds good enough for you, and dns and network ports can be done later?

db1022 is no longer. removed from site.pp, all dns is removed, killed in puppet, changed racktables, wiped disks, removed from rack

JFTR: The host was still showing up in puppetdb (e.g. via https://servermon.wikimedia.org/hosts/). I ran "puppet node deactivate db1022.eqiad.wmnet" on puppetmaster1001, that should properly remove it.
