Comment (by anarcat):

 GR did step 6, 7

 hiro did step 8 and 9: switched DNS in LDAP, nagios, reran ud-replicate
 and puppet on puppetmaster, grepped for IP in dns (no match)

 i redid part of 1: i had forgotten the DRBD switch.

 then we stumbled upon new problems:

  * puppet couldn't run because of post-buster manifest errors (hiro fixed
 this)
  * redis wasn't listening on the wrong port (anarcat fixed this by
 restoring the old config from backups)

 The redis config was lost somewhere in the process which is somewhat
 worrisome. Hopefully it's the only thing that was lost.

 We're at "post step 9" which is undocumented, but it's basically:

  10. test (GR)
  11. retire old machine (TPA, step 12-13 in the ganeti procedure)
