I have a CUCM cluster (One Publisher and one Subscruber) after a disaster on the infrastructure, it happened that I lost the Publisher node, the VoIP system is now running only on the Subscriber.
In order to rebuild the Publisher I installed a new VM with CUCM same exact version, network parameters and credentials as the old Publisher.
In order to backup the Publisher I saw that I can do it either by: Backing up the new Publisher from the existing Subscriber, or Backing up the new Publisher from a DRS backup took before the disaster, Which option is the best in order to rebuild the Publisher? Does any of these options will recover licenses as well or they are lost anyways ?
Also I found that in order to bring the Publisher up I need to stop the replication from the Subscriber, does this enough to avoid loosing the database from the subscriber if I bring up the new "empty" Publisher ?
Any help would be much appreciated.
Solved! Go to Solution.
Assume that your meaning a restore of the Publisher, not a backup? If so the best option in my opinion is to do a restore from a good DRS backup. If you don’t have a backup that is good, the option to restore the database from the subscriber is your only option. The reason for why DRS is the best option is that it restores more than “just” the database. On the question about licenses, to answer this you’ll need to share what version of CM that you have?
Everything worked with restoring the subscriber, thank you for your help.
My concern now is with the PLM, it shows the licenses fulfillment but in the PLM it can't synchronize with the product instance and it shows "Registration Conflict" ! Also in the CUCM it shows that it's running with demo within 60days
Any help would be much appreciated
