< T218729: Migrate deployment-prep away from Debian Jessie to Debian Stretch/Buster | T327742: Migrate deployment-prep away from Debian Buster to Bullseye/Bookworm >

Jessie has now been removed from deployment-prep (just about 1 year and 4 months after the deadline, let's try to be faster this time). As production starts moving away from Stretch, it's time for us too to start removing Stretch instances.

Few notes:

• Extra LVM storage has been deprecated in favor of Cinder storage. Feel free to ask the cloud-services-team for quota increases.
• Consider writing documentation for moving and maintaining those services!
• Codesearch now includes Puppet data in Horizon, you can use that to find references to existing VMs.
• New instances will only have instance-name.deployment-prep.eqiad1.wikimedia.cloud names, they will _not_ have any names under .wmflabs.
• See also T276650: Re-consider setting up a Kubernetes cluster on the Beta cluster
