'm afraid this change can affect ipMonitor SSL configuration, credential, etc.
Credentials will not be affected. You may want to do a "backup now", but this change won't affect anything we really count on.
Before: Park the license. I don't know if you have to, but it's just a few clicks ...
After: Grab the license, then do another self signed certificate. Ensure that the new computer's name doesn't have "_" and "*" in the name, and it'll work out fine. Note: We're finding out that the OS's Certificate lookup fails if those characters are in the common name.
Other than that, there are no special details to know.
