Reference ticket for when they were upgrade to buster: T255026: Upgrade schema[12]00[12] to Debian Buster
These are 4 VMs, 2 in eqiad and 2 in codfw
- schema1003.eqiad.wmnet
- schema1004.eqiad.wmnet
- schema2003.codfw.wmnet
- schema2004.codfw.wmnet
Since the last time these were upgraded, our reimaging cookbook has been adapted so that it works with VMs and this means that they can be upgraded in place.
This should make it even easier to upgrade them. There are no custom applications running on them, it is just nginx and a git::clone which is all managed by puppet.
Tagging Event-Platform and Data-Engineering for visibility, but I would expect that Data-Platform-SRE will be carrying out the upgrades.
