These instructions describe how to upgrade Stingray Traffic Manager Software instances. For instructions on upgrading on other platforms, please refer to Upgrading Stingray Traffic Manager.
You can upgrade a running copy of the Traffic Manager software with very little downtime. There are two ways to perform the upgrade: using the Administration Interface, or using the command line.
The upgrade procedure:
The downtime is rarely more than one or two seconds. If necessary, you can then install a new license key file using the Stingray Admin Server, for example, to enable new product features.
Upgrading via the Administration Interface
The upgrade program automatically stops your existing version of Stingray Traffic Manager, upgrades it, and restarts it, keeping all your existing configuration.
If you have a cluster of traffic managers, you can upgrade each one in turn. Do not make any configuration changes until you have upgraded the entire cluster to the same software version.
You can use the 'rollback' script to revert back to a previously installed version of Stingray software, or to roll forward to a later version that you installed previously:
You will then be shown a list of the different software versions that you have installed, and asked to chose which one you would like to roll back or forwards to. When you roll back (or forwards) to a different version, the software will use the configuration that was last active with that version. For example, If you upgraded from version 8.0 to version 8.1 two weeks ago, then roll back to version 8.0, it will use the configuration that version 8.0 last used two weeks ago.
