Upgrade to a new version of Cloud Connector
Learn about how to upgrade your Cloud Connector Edition deployment.
If you have set up an online management tenant account and enabled automatic updates, your existing deployment of Skype for Business Cloud Connector Edition will be upgraded to the newer version automatically—according to your automatic update time window configuration. You can also perform a manual upgrade.
Cloud Connector Edition versions 1.4.1 and later perform automatic updates by default. If you want to upgrade to the latest version (2.1) manually, see Upgrade a single site to a new version later in this topic.
Automatic update requires that the Cloud Connector service is running. The following steps describe the process for automatic updates:
The automatic update process will run according to the schedule you have configured for automatic updates.
Operating system update tasks
Check and download operating system updates to all Cloud Connector VMs.
Install and update all Cloud Connector VMs one by one and restart.
After the Cloud Connector VMs restart, check to see if another restart is needed.
After the Cloud Connector VMs have been successfully patched, repeat the process for the Cloud Connector host machine.
After the Cloud Connector host machine successfully boots up, any outstanding operating system update tasks are completed.
Cloud Connector update tasks
Download and check the version file from the download site.
Download the new version .msi file.
Uninstall the old msi file; install the new msi file.

When Cloud Connector updates to a new build, Cloud Connector cmdlets might not be updated. This can happen, for example, if a PowerShell window is left open while automatic update occurs. To load the updated cmdlets, you can do either of the following steps:> Close PowerShell on the Cloud Connector appliance, and then reopen PowerShell.> Or, you can run Import-Module CloudConnector -Force.
Upgrade a single site to a new version
If there is only one appliance in the site you want to upgrade, do the following:

You cannot use the .ini file from a previous release.

Follow the steps for upgrading a single site, upgrading one site at a time for each site in your deployment. Make sure and Validate your Cloud Connector deployment after upgrading each site.
