Release Notes for Cisco CDA Visual Quality Experience Application Release 3.10
Installing VQE Release 3.10 Software
To run the VQE incremental upgrade installer to upgrade an earlier VQE Release 3.X release to
Release
3.7.X, do the following:
Caution To be safe in case of a catastrophic failure, be sure to backup configuration files as described “Backing
Up VQE Release 3.X Files Before Upgrading or Installing Software” section on page 12.
Step 1 If needed, log in as root on the CDE111/ CDE250 2V0 server where the VQE incremental upgrade
installer was downloaded.
When you run a VQE incremental upgrade installer, you must have root privileges.
Step 2 Run the VQE incremental upgrade installer. For example:
[root@system]# /tmp/vqes-3.7.x-x.bin
The VQE incremental upgrade installer determines the current VQE software version, performs a sanity
check on the existing VQE software, checks for the existence of needed configuration files, and does one
of the following:
• If the preceding checks determine that there is a problem, the VQE incremental upgrade installer
informs you that an ISO installation is required and exits.
• If the preceding checks determine that all is well, the VQE incremental upgrade installer displays:
You are currently running VQE version 3.x.x.
Do you want to install version 3.7.x (build xx) now? y/[n]:
Step 3 To install the software, enter y and press Enter.
The VQE incremental upgrade does the following:
• Upgrades/installs/uninstalls RPMs (as needed) and installs associated default configuration files.
• Performs installation post processing as follows:
– Installs a new vcdb.conf.sample in the directory /etc/opt/vqes/.
– Saves a set of factory default /etc configuration files associated with the RPM installation in the
directory /vqe-etc/etc-pristine/.
• Runs the VQE Configuration Engine to apply VCDB values to the configuration files under /etc.
After the upgrade process completes, you can examine the /var/log/upgrade.log file to look for warning
and error messages, and to find out if there were any configuration files (from your previous installation)
whose contents were not completely applied to the new release.
The set of /etc configuration files from your previous installation are archived in a tar file in /vqe-etc/
prior to the upgrade. You can manually apply the values from these old configuration files if these
configurations must be restored.
