Upgrading a VM VCS
When upgrading a VM VCS you must use a .tar.gz file (available from the software download site), not an
.ova file:
.ova file:
1. To avoid any performance degradation we recommend that you upgrade the VCS while the system is
inactive.
2. If the VCS is part of a cluster or is using provisioning or FindMe, follow the relevant Cisco VCS Cluster
Deployment Guide.
3. If the VCS is not part of a cluster and is not using provisioning or FindMe:
a. Log in to the VCS VM web interface as an administrator.
b. Backup the VCS from the

Backup
page (

Clustering for resilience and capacity
When clustering VM VCSs it is strongly recommended to use at least two physical hardware hosts –
clustered VCSs are designed to support resilience and capacity.
clustered VCSs are designed to support resilience and capacity.
To support hardware resilience, VCS peers must run on at least two different hardware platforms.
Each and every VCS peer in a cluster must be within a 15ms hop (30ms round trip delay) of each and every
other VCS in or to be added to the cluster.
other VCS in or to be added to the cluster.
Migrating from a physical appliance to a VM
If you are migrating from a physical appliance to a VM VCS, the backup/restore process (
Maintenance
> Backup and restore
) can be used to transfer configuration between the two installations. Note that you
will receive a warning message, but you will be allowed to continue.
Supported features
vMotion
vMotion has been tested and VCS will move (migrate) successfully. If you need to move VCS to a new host
you must perform a host migration via vMotion.
you must perform a host migration via vMotion.
There may be glitches (packet loss/jitter) in media for calls that are interworked by VCS as the VM is moved.
We recommend that a vMotion move is carried out when there is low call activity on the VM VCS.

SAN with Fibre interconnect
Use of a SAN with Fibre interconnect, rather than a NAS, is recommended in order to maximize the transfer
speed.
