Comment (by hiro):

 This is a possible timeline for migrating the CRM machine (to be confirmed
 with GR)

  1. libvirt-import, renumber-instances, DNS TTL, DRBD change, implies few
 minutes downtime, anarcat, wed 8th
  2. hack at ipsec, anarcat, wed 8th
  3. test, anarcat, wed 8th
  4. buster upgrade, hiro, thu 9th
  5. test, hiro, thu 9th
  6. put Drupal in maintenance mode on old CRMs, GR, wed 15th
  7. sync mysql and uploads, GR, wed 15th
  8. shutdown old CRM, hiro/anarcat, thu 16th (step 8 in the ganeti
 procedure)
  9. final DNS change, hiro/anarcat, thu 16th (step 11 and 12 in the ganeti
 procedure)
