Unity Connection failover during upgrade

We are upgrading from Cisco Unity Connection pair from Version 8.5.1.ES65.13900-65 to 8.6.2.21900-5.  We want to limit downtown.  Curious if service remains up on the secondary server while reloading to the upgraded partition, then vice-versa?

Unity Connection failover during upgrade

Hi there,

This depends on the "refresh" upgrade portion of the puzzle

Your 8.5 version may already have the .cop file installed which would change the duration

of the outage;

This is the .cop file

ciscocm.refresh_upgrade_v1.1.cop.sgn
Release Date: 14/OCT/2011
COP file for refresh upgrade paths to 8.6(1). In addition this COP file permits the upgrade to recognize the unrestricted upgrade media or file. This is for UCM, Unity Connection, CUCMBE5k (and IME).
Size: 82436.80 KB (84415280 bytes)

Here are the install notes;

Installation Instructions

File Name: ciscocm.refresh_upgrade_v1.1.cop.sgn

MD5 Sum: b295f4e56c9fb93856b71b05b7a65456

*** The patch installation should be done off hours during a maintenance window because there is a slight risk that installation during normal business hours could temporarily impact system performance.  The patch installation should occur when there is no other CLI or GUI activity on the system since the patch will terminate all CLI and GUI sessions and restart the Tomcat service. ***

  1. Install this file on all nodes in the cluster from the "Install/Upgrade"      option under "Cisco Unified Communications Operating System      Administration."
  2. Once patch is successfully installed, allow the system      a few minutes for the Tomcat service to completely restart before proceeding      with the Refresh Upgrade and for the CLI command “show version active” to      display the results correctly.

*** Some ES and SU versions have all the changes delivered by this patch.  If that’s the case, the patch install will fail with an indication that the current version already contains the necessary changes to support a successful Refresh Upgrade to 8.6(x). ***

*** No reboot, restart of the system or restart of any services is required after the patch has been installed.  The GUI or CLI will indicate that a system reboot is required.  For this patch file only, that message can be disregarded. ***

*** If upgrading from a 6.1(4) or 6.1(5) or 7.1(3) version to an 8.6(x) UNRESTRICTED version, only this patch is required.  It is NOT necessary to also install the ciscocm.allow_upgrades_to_unrestricted.cop.sgn patch.***

*** Once this patch is installed, the email notification feature presented on the GUI and CLI will only be fully functional if upgrading to 8.6(x) release.  It will not be fully functional if installing another COP file or upgrading (L2) to an 8.5(x) or earlier release.  ***

Re: Unity Connection failover during upgrade

Thanks Rob! We do have to install the cop file. I’ll read through those links.
