I want to have m1 upgraded to Buster and Mariadb 10.4
- db1135 master
- Provision db1097 as future master.
- db1117 slave (across all miscs)
- db2078 (already migrated)
The idea is to grab one of the hosts at T253217 and migrate one of these as they have smaller disk (but still enough for misc) and keep the current master as a rollback plan just in case.
Once migrated, move the "old" m1 master to the list of pooleables hosts and move those to sXX as they have more disk space (4.4T vs 3.2T)
