If you chose this option, and the upgrade process fails, use the following procedure to revert to the earlier
product version and configuration:
To complete this process, you must have access to the product installer and license key or license file for
the earlier Cisco Prime Network Registrar version. Any attempt to proceed otherwise may destabilize the
product.
If the installer had successfully performed the upgrade but you want to roll back to the earlier version at
some later point, this procedure can result in network destabilization and data loss; for example, you will
lose updates made to the Cisco Prime Network Registrar database after the upgrade, including DHCP
lease data and DNS dynamic updates.
Caution
Step 1 Verify that the archive directory that you specified during the upgrade process exists and is valid. These examples assume
the default archive location provided during installation. Ensure that the path to the cnr_data_archive directory reflects
the value of the archive directory that you specified during installation. If you are using:
•
Windows
—
C:\NetworkRegistrar\
{Local.sav | Regional.sav}
•
Linux
—
/opt/nwreg2/{local.sav | regional.sav}
Step 2 Uninstall Cisco Prime Network Registrar using the procedure described in the Uninstalling Cisco Prime Network
Registrar, on page 37 .
Step 3
Other than the contents of the specified archive directory, delete any remaining files and directories in the Cisco Prime
Network Registrar installation paths.
Step 4 Reinstall the original version of Cisco Prime Network Registrar. Ensure that you follow the reinstallation procedure
described in
Cisco Prime Network Registrar Installation Guide that is specific to the original product version.
Step 5
After the installation ends successfully, stop the Cisco Prime Network Registrar server agent:
•
Windows
—
Local: net stop nwreglocal
Regional: net stop nwregregion
•
Linux
—
Local:
◦
RHEL/CentOS 6.x
—
/etc/init.d/nwreglocal stop
◦ RHEL/CentOS 7.x — systemctl stop nwreglocal
• Linux — Regional:
◦ RHEL/CentOS 6.x — /etc/init.d/nwregregion stop
◦
RHEL/CentOS 7.x
—
systemctl stop nwregregion
Step 6
Delete the contents of the Cisco Prime Network Registrar install-path/data subdirectory.
Step 7 Extract the contents of the backup file to the reinstalled version of Cisco Prime Network Registrar.
a) Change to the root directory of the filesystem. On Windows, this directory would be the base drive (such as C:\); on
Linux, it would be /.
