nembus and neptunium have been replaced by seaborgium and serpens. They can now be decomissioned or reclaimed to spares. These were our old ldap systems until the week of 2015-12-14.
Each system will have to have all the following steps:
**nembus:**
[x] - system placed into maint/downtime in icinga
[x] - all puppet repo entries removed - https://gerrit.wikimedia.org/r/#/c/260522/
[x] - production dns entries removed - https://gerrit.wikimedia.org/r/#/c/260523/
[x] - system powered down
[x] - switch port disabled / vlan removed
[x] - puppet/salt keys revoked (both palladium and neodymium) as well as puppetstoreddb
[] - system wiped
[] - system added back to spares sheet
**neptunium:**
