Note
•
If you are running the Authoritative DNS server, the upgrade process (from Cisco Prime Network
Registrar pre-8.2 to 9.1) could take a while depending on the number of zones and resource records
because of the database changes made to Cisco Prime Network Registrar 8.2.
•
There are several significant changes with respect to DHCP failover support when upgrading from
a version prior to Cisco Prime Network Registrar 8.2 to Cisco Prime Network Registrar 8.2 or later.
For more information, see the
Upgrade Considerations for DHCP Failover
section in
Cisco Prime
Network Registrar 8.2 Installation Guide
.
•
Either cluster of a DHCP failover pair can be upgraded from Cisco Prime Network Registrar 8.2 to
Cisco Prime Network Registrar 9.1 and operate successfully with the other cluster that is running
Cisco Prime Network Registrar 8.2. You must not run the DHCP failover cross-version for an
extended period, and must upgrade both the main and the backup clusters to Cisco Prime Network
Registrar 9.1 at the earliest.
During an upgrade, Cisco Prime Network Registrar now displays any pre-existing HTTPS configuration
defaults for the keystore filename and password to enable a secure connection for web UI logins. If you have
enabled HTTPS, and are unaware of the keystore filename and password at the time of the upgrade, you can
preserve HTTPS connectivity during the upgrade, and re-enter the defaults when prompted.
DNS Upgrade Considerations
Before upgrading from a pre-8.2 to 8.2 or post-8.2 version:
•
Staged edits will be lost after the upgrade. All the staged edits must be synced to DNS before upgrading.
•
RR upgrades are sourced from a valid AUTHZONE.db. If that database is corrupt, missing, or incomplete,
the resulting upgrade will miss some or all RRs. The most common situation is upgrading from a shadow
backup or database backup, or a dataset that needs to be rebuilt.
•
Ensure that the database is fully operational before upgrade.
Upgrading on Windows
To upgrade to Cisco Prime Network Registrar 9.1:
Step 1
Ensure that your environment meets the current system requirements (see
System Requirements, on page 7
).
Step 2
Use the currently installed release to complete any configuration changes in progress, so that the existing database is
consistent before you perform the upgrade.
Step 3
Uninstall the previous version of Cisco Prime Network Registrar. Your existing configuration data will remain in place
after the uninstall.
Step 4
Back up your Cisco Prime Network Registrar data on a different machine or a shared network device and upgrade your
operating system to Windows Server 2012 R2. See documentation supplied by Microsoft for information about how to
install/upgrade Windows servers.
If you install Windows Server 2012 R2 instead of upgrading and the disk is reformatted, you must restore the
Cisco Prime Network Registrar data to the C:\NetworkRegistrar\{Local | Regional}\data folder.
