Today I learned that if you are switching from the legacy version of ASR to the new version of ASR, the Mobility Service version has a new revision, which would be expected. However, you have to manually uninstall the older version from the servers you wish to protect. Otherwise, the “push” installation just fails and doesn’t report anything really useful in the Azure portal.
When I went to manually install it on the server, I got better error messages from the application noting that a previous version of the service was installed and needed manual removal.
Perhaps I’ve just saved you some time one day.
