Use this feature to upgrade an existing Communication Manager template to a later Communication Manager release. You can upgrade only custom templates. This feature supports upgrading a Communication Manager agent or endpoint template from an earlier Communication Manager release to a subsequent Communication Manager release. You can also upgrade templates across multiple releases.
This feature does not support downgrading of template versions.
When you perform the upgrade operation, note that:
System migrates the existing template settings to the new template version.
System sets the new parameters in the new template version to default values.
System deletes the deleted parameters in the new template version as compared to the older template version.
System makes the new keywords available for editing within the new template, but the upgraded template retains the previous keyword setting, if available. If the previous keyword is not available, then the default is used in the upgraded template.
After you commit a template upgrade task, the system upgrades the template and enlists the newly upgraded template on the Template List.
