[cisco-voip] Upgrade from CCM3.3 and CRS 3.1 to CCM5.1 and CRS4.5

Fri Jan 12 12:26:50 EST 2007

Hey, and if I had kept reading that page,

"

For CRS 4.5(2), be aware of the following:

•CRS is implemented as a standalone server with no support for high
availability.

•CRS 4.5(2) in the Cisco Unified Communications contact center environment
can only be handled as a "fresh" installation; upgrading from the previous
CRS system is not supported. You cannot upgrade to CRS 4.5(2) from CRS
Releases 3.1, 3.5 or 4.0; only a fresh install of CRS 4.5(2) is supported.
------------------------------

*Note *However, you can upgrade from CRS 4.5(1)SR1 to CRS4.5(2).
------------------------------

•CRS 4.5(2) also does not support data migration of configuration, scripts
and agent information from CRS Releases 3.1, 3.5, 4.0 or 4.5(2). You must
manually rebuild existing configurations and CRS scripts on the freshly
installed CRS 4.5(2) server.

•Configuration data and CRS scripts (both custom and standard) are stored in
the CRS database; not in the LDAP directory on the Unified CallManager.

•You should migrate all CRS applications that were previously co-resident
with the Unified CallManager to a different Cisco Media Convergence Server
(MCS).

•You must use the new "Backup and Restore System for CRS4.5" utility to back
up CRS data.

•Ensure the following:

–A valid DNS server is available to provide name resolution services for all
cluster machines, including CRS machines.

–A backup server is available for exclusively backing up the CRS database
and is not used to back up other applications.

–The BARS server is bundled and installed on the same CRS server or on a
separate MCS server acting as the backup server."
