You can upgrade VMware Identity Manager Connector online or offline.
By default, the connector uses the VMware Web site for the upgrade procedure, which requires the connector appliance to have Internet connectivity. You must also configure proxy server settings for the connector appliance, if applicable.
If your connector instance does not have an Internet connection, you can perform the upgrade offline. For an offline upgrade, you download the upgrade package and set up a local Web server to host the upgrade file.
The following upgrade paths are supported:
From version 2.3 , 2.4, 2015.10.1, or later to the latest version available
