isn't that command only if you want to revert back to a newer version? Also, the problem relies on our Unity servers and not Communication Manager. CCM upgraded without a problem.

Thanks in advance,

Hi I had this same issue today where I received a "sync after switch failed" error. The problem turned out to be with DNS, make sure you are able to resolve the hostname of the server, not just it's fully-qualified-domain-name (FQDN).

For example if your server is named SERVER1, make sure SERVER1 resolves, and not just SERVER1.domain.com.

With my server, SERVER1.domain.com was resolving, but not SERVER1. Once I added an entry in DNS for SERVER1, I was able to switch versions without issue.
