(Post updated on 3/26/2020 to add more information about installation process)
We wanted to let you know that we are releasing what we consider a significant update to Exchange Hybrid Configuration Wizard (HCW). Along with a handful of small bug fixes, there are four major changes coming that we wanted to share with you:
Because this is a major version update, the build begins with 17.x vs 16.x. The build number can be found in the top right corner once you download and open the HCW.
Because of the web-based distribution nature HCW uses and this version is a brand new package, you will get all this goodness simply by installing the new HCW from here. The current builds of HCW (16.x) will not automatically update to 17.x build, in fact – you could run the two side-by-side. Once you are on 17.x build – the HCW will then auto-update as usual.
A few additional notes: At this time, we do not anticipate new HCW 16.x builds. Therefore, to continue getting new HCW builds in the future, uninstall the current version of HCW (16.x) and then install the new version (17.x). The new version of HCW has a new dependency, .NET 4.7.2. The installer should take care of this for you, but just so you are aware.
On installation of the new version of HCW
Generally speaking, the HCW is a standalone, stateless app that gathers configuration information and applies the necessary changes to get to your topology into the desired state. These changes are applied at the Exchange Organization level (both on premises and in the cloud/tenant configuration). Those settings are not stored or managed by the HCW after the run has completed. The Hybrid Agent, once installed and configured runs on the specified machine and is also not tied to the HCW app after installation completes.
Unless you need to re-run HCW, there is actually no need to uninstall and reinstall the new version. In fact, once hybrid is configured, the HCW itself could be uninstalled and it would have no effect on the hybrid configuration it deployed.
In case that at some time you want to re-run HCW, you would want to run the latest version… and that is why we mentioned that you should uninstall the 16.x version and install the 17.x version. But if you do not plan to re-run HCW, you do not need to actually do anything.
