====== 20220920 / migration update ======

Planning is fluid.

in order to :
  * make room for “Cascade part 2” servers (~80 nodes)
  * better placement of scratches (in rack)
  * add scratch/Cral to Cascade
  * enable 4 new visualization servers (probably in Lake)
  * moving and filtering out E5 nodes (for deb11+slurm)

we need to :
  * stop and move scratch/Cascade to another rack
  * re-cable Cascade s92node[65-78]
  * re-cable Cascade infiniband network
  * power off and de-rack E5 nodes

Some of it will be done right after "Acoustics Measurements" (see next news).

<note warning>**IMPORTANT NEWS**
Debian9/SGE will be shutdown definitely Friday 21th of October 2022.
