In 2024 Netops and DC-ops completed the upgrade of the network switches in all codfw racks to newer equipment.
You can find all the information on https://wikitech.wikimedia.org/wiki/Vlan_migration
All new servers are by default getting in those new vlans, but to not have to wait for a full 5+ years server refresh cycle, we're now asking service owners to re-image their existing baremetal servers using the --move-vlan cookbook parameter, at their own pace/convenience. This will change the server's IP.
There will of course be some special cases (like Ganeti, or DBs) and that's ok to not covert 100% of the servers, but the most we can get, the better.
Please contact netops for any help.
