Upgrade the VMware Enterprise Systems Connector from the AirWatch Console to take advantage of the latest bug fixes and enhancements. This process can be automated using the VMware Enterprise Systems Connector auto-update option, or performed manually for situations where administrative control is a priority.

VMware Enterprise Systems Connector Auto-Update

While you are installing VMware Enterprise Systems Connector, by default, the auto-update check box is selected. Auto-update allows VMware Enterprise Systems Connector to upgrade automatically to the latest version without any user intervention by querying AirWatch for newer versions of VMware Enterprise Systems Connector. AirWatch recommends that you allow auto-update (do not de-select the checkbox), but AirWatch made this optional for those environments and situations in which manual upgrades are preferred.

Benefits

  • No need to determine manually if you need to upgrade and then have to search for the latest VMware Enterprise Systems Connector version – the software does it for you.
  • Since it assures you stay updated, you always have the latest features, enhancements and fixes.
  • Most importantly, it ensures you have the most up-to-date security.

Update Process

VMware Enterprise Systems Connector auto-update is performed using the Bank1 and Bank2 folders inside the CloudConnector folder. AirWatch detects which of these folders is empty and streams the appropriate VMware Enterprise Systems Connector files into it, in addition to emptying the contents of the other folder. For the subsequent update, AirWatch repeats the process except for the alternate folder. This process repeats each time a new version is auto-updated. This process is illustrated below.

Important:

 Do not delete the Bank1 or Bank2 folders. The Bank1 and Bank2 folders are integral to the VMware Enterprise Systems Connector auto-update process.

Auto-Update Security

VMware Enterprise Systems Connector auto-updates are performed with security in mind. Every update is signed by the AirWatch Console and verified by VMware Enterprise Systems Connector, so it will only update itself with a trusted upgrade. The upgrade process is also transparent to the AirWatch Admin. When a newer version is available, VMware Enterprise Systems Connector knows from querying the AirWatch Console on port 443, and then an upgrade occurs.

While VMware Enterprise Systems Connector is upgrading to the latest version, it will not be available, so there will be a short loss of service (i.e., approx. 1 minute). For those who have multiple VMware Enterprise Systems Connector servers, to ensure all VMware Enterprise Systems Connector services are not down at the same time, AirWatch incorporates a random timer to the upgrade process so VMware Enterprise Systems Connector outages will occur at different times for very short periods of time.

If the VMware Enterprise Systems Connector auto-updates, the version under Add or Remove Programs does not change – the original version will still be listed. The version under Add or Remove Programs only changes when you run the full VMware Enterprise Systems Connector installer. The best way to verify if the auto-update succeeded is to look in the VMware Enterprise Systems Connector logs for what version is running.

Effects of Disabling Auto-Update

If you choose to disable this feature, then there are some drawbacks by having to do all VMware Enterprise Systems Connector upgrades manually. If VMware Enterprise Systems Connector is not upgraded, it will continue to remain operational until any one of the following occurs:

  • If VMware Enterprise Systems Connector is powered Off and then On (purposely or power outage).
  • If VMware Enterprise Systems Connector needs to be reinstalled.
  • If AirWatch Console is upgraded to a later version.
  • If AirWatch, AWCM, or VMware Enterprise Systems Connector certificates are regenerated, which would then require the latest version of VMware Enterprise Systems Connector installed and a reboot to recognize the new certificate(s).
