Downgrade configuration data
Both
Minor and
Major Server Edition downgrades are supported, however for a major downgrade you need to install
Server Edition again:
Review the release notes of the current version before you downgrade.
Take a backup of the solution backup from Web Manager of Server Edition Primary before you downgrade. The backup should include all systems, components and configuration data sets.
Perform downgrade when there is no traffic on the system because it affects the service of the system.
Minor downgrade is a downgrade from one previously installed minor release to another in the same series. For example: 8.1 SP to 8.1 SP or 8.1 SP to 8.1 GA
Minor Linux server downgrade can be performed using the Web Manager package manager by qualified personnel only for the following IP Office components: IP Office, Jade Media Server, Avaya one-X® Portal for IP Office, Voicemail Pro Server or client, Web Control and Web Manager. You cannot downgrade any other component.
You can perform a Minor Linux server downgrade by performing a complete reinstallation and re-ignition.
You can perform a Major Linux server downgrade, for example, a downgrade from 9.0 to 8.1 or from 9.1 to 9.0 GA only by reinstallation and re-ignition. Do not attempt to downgrade a component through the Web Manager. In addition, all servers require downgrade because IP Office Server Edition Solution does not support mixed versioning.
You can downgrade Server Edition Expansion System through the IP Office Manager memory card Restore command.
After you downgrade, to restore the corresponding backup, use Web Manager.
Note:
For Release 8.1 when you restore the system through Web Control, the system does not restore IP Office Security settings for any device other than Server Edition Primary . To restore the IP Office configurations, use the configuration synchronization feature of IP Office Manager .
Ensure that all components of a Server Edition deployment have the same software version.
Subsequent upgrade of a Minor or Major downgrade are supported
Note:
Avaya reserves the right to change Server Edition downgrade policy at some time in the future.
When you downgrade, the system does not downgrade the configuration data of the component automatically when the new version is initially executed. You need to restore the correct configuration version or administer new configuration data.
To achieve IP Office configuration reuse where no corresponding backup data is available, use the CSV export/import feature of
IP Office Manager:
Read the latest configuration into IP Office Manager offline. IP Office Manager supports all configuration versions up to its own version.
Export configuration using File | Import/Export | Export, CSV, All of the configuration
Default the configuration on the target system and read into IP Office Manager.
Import each configuration using the File | Import/Export | Import, CSV, All of the configuration.
Check/correct errors and warnings.
Check configuration settings are as expected.
Send to system and check operation
For a IP Office Server Edition Solution , the process should start with the Primary, then secondary then expansion systems. Each should be done individually using Manager in ‘standard’ not IP Office Server Edition Solution mode.
