Release Notes for Cisco CDA Visual Quality Experience Application Release 3.10
Installing VQE Release 3.10 Software
Note If there are manually edited files in the existing /etc directories, the changes were made by an
administrator without the use of VCDB. If you want to continue to have these differences present in your
configuration files, you need to carefully edit the relevant configuration files so that they include the
items that are different.
• Backs up the /etc configuration files to the vqe-release-hostname-timestamp.tar.gz file by creating
a tar file archive of the following files: /vqe-etc/etc-diff, /var/log/upgrade.log and all files under /etc.
Saves the tar file archive in a temporary set of files.
• Formats the hard drive.
• Installs the Linux operating system and add-on RPMs of VQE packages and configuration files.
• Restores (from the tar file archive) the following /etc configuration files that were present on your
earlier VQE Release 3.X host:
– On a VQE-S host, the VCDB configuration file (/etc/opt/vqes/vcdb.conf)
– On a VQE-S host, the channel configuration file (/etc/opt/vqes/vqe_channels.cfg)
– On a VQE Tools host, the channel configuration file (/etc/opt/vqes/vqec_channels.cfg) and all
VCPT configuration files in /etc/opt/vcpt/data
– On both VQE-S and VQE Tools hosts, all files in the /etc/opt/certs directory (files related to
Secure Sockets Layer certificates)
Note Except for the preceding files, all other /etc configuration files from an earlier Release 3.X VQE host
are not copied to the directories under /etc.
• Saves the other files shown in Table 5 to the CDE111/ CDE250 2V0 hard drive.

– Installs a new vcdb.conf.sample file in the /etc/opt/vqes/ directory.
– Saves the factory default configuration files under /etc to the directory /vqe-etc/etc-pristine.
• Performs a final reboot. As part of the final reboot, runs the VQE Configuration Engine to apply the
VCDB values (from earlier VQE Release 3.X vcdb.conf that was restored earlier) to the VQE 3.10
configuration files under /etc (including vcdb.conf).
