====== 20220908 / migration update ======

**deb9 -> deb11 migration update**

We are powering off old E5 cluster, by queues, to:
  * make room for "Cascade part 2" servers (~80 nodes)
  * moving and filtering E5 nodes we will keep active (in deb11+slurm)

test nodes for E5/deb11+slurm will be drain of jobs and powered off soon to make room for real E5 production nodes (upgraded to deb11+slurm).

A block of nodes (~24n, 768c) will be added to Lake partition, without scratch, next week.
