[cisco-voip] Disaster Recovery Procedure CUCM 5.1(2)

Hello,

I had to do a Publisher replacement from a MCS7825 to a MCS7835 last
week. We had two additional subscribers. I followed step by step the
guide Wes has mentioned and all went fine (the whole change took us 9
hours).

The main problem is that you MUST reinstall also all the subscribers
from the cluster: this was confirmed by TAC and by the customer's SE
cisco engineer.

If you have any additional question about this just drop me an email...

Regards,

Ruben

Hi Patrick,

Good stuff.  Most of this is finally covered in CM513 docs:

ws: you restored the pub only, correct? and rebooted?  after you 
reinstall sub will need to DRS restore it as well.

ws: this comes later actually. check the doc, you will create new CTL

step5: reinstall subs, then restore subs, then perform post-replace
