Add an X5 Cisco VCS to a Cisco VCS X5 cluster
Follow this process if you have an existing X5 cluster to which you want to add a Cisco VCS. If you do

Note: You can include up to 6 Cisco VCSs, including the master Cisco VCS, in a cluster.
This process will add the X5.x Cisco VCS to the cluster and replicate the cluster Master’s configuration

Note: Cisco VCS clusters peers should all run the same version of code, for example all X5.0, or all

components, all Cisco VCS peers must be upgraded – including the Cisco VCS being added to the

During this upgrade process there will be the opportunity to merge this new Cisco VCS’s FindMe
accounts into the FindMe database for this cluster, provided that this Cisco VCS is already
replicating its FindMe information with Cisco TMS.
FindMe information can only be kept if the relevant Cisco VCS is already configured to operate
with Cisco TMS and is configured with Enable TMS Agent Data Replication. (FindMe

3. Check that the Cisco VCS is running X5 (or later) software and that the software version is
identical to the version running on the other cluster peers.
4. Backup the Cisco VCS (See Appendix 1 for details).
