Upgrade Overview
Upgrading is a process for migrating data, converting database content to be compatible with
updated software. Please review any release notes for your new version before assuming migration is
necessary or possible. Not all upgrades require migration tasks, and migration is not possible from/
to all versions.
New software is not always capable of using data from older versions. Some data may be lost to the
application or cause system errors if not properly upgraded. This migration process is designed to
extract legacy data while the old software is operational and then transform this data to be
compatible with the new software. You may follow the steps outlined here to preserve existing data
when upgrading. Since migration addresses the entire application’s database, you only need to do
this once for the entire system.
CAUTION:
When upgrading, you must upgrade all servers since they all need to run the same version of code. If
your operating system is not supported in the upgrade version, you must upgrade to a supported
operating system before upgrading OpenManage Network Manager. See Compatible Operating
Systems/Databases/Browsers on page 96.
Restart / Resync Between Version Upgrades
After each migration stage, restart the OpenManage Network Manager application server and web
portal, and resync discovered devices. This is especially true for multi-staged upgrades (5.3.8 to
6.0.4 to 6.1.2, for example).
Unicast and Upgrades
Unicast for intra-cluster communication depends on configuring /oware/jboss-X.X/
server/oware/deploy/cluster/jgroups-channelfactory.sar/META-INF/
jgroups-channelfactory-stacks.xml
. Upgrade overwrites this file. If you upgrade, copy
the file configured as you might like to a separate location, then return it to its correct location after
the upgrade.
Licenses and Upgrades
If you are upgrading your software, you must install licenses for any new functionality (refer to the
OpenManage Network Manager User Guide for instructions). If you have downloaded a standard
package, but are upgrading from a previous system with upgraded capabilities—for example, the
rights to manage more than the standard number of devices—you may also need to upgrade that
standard package’s licenses.
Recovering licenses—Dorado Software can provide licenses to replace any lost or
misplaced on request.
Updating license keys before upgrade—Use the same channel to get the upgraded
license.
You can contact the Sales rep that provided the license, contact Dorado Software or call the Dorado
Software help desk, or submit a trouble ticket requesting a license upgrade.
When you license new features, you must log out, then re-log in for the new license to take effect.
On rare occasions, you must restart the application server.
CAUTION:
Upgrading from previous versions may change device Model numbers. You may need to change any pre-
existing features (for example: filters) that refer to model numbers.
