I migrated from Exchange 2010 to 2016, I am trying to unistall Exchange, demote my "old" server to performe a clean install and then install Exchange 2016 and migrate it back to the "old" server.

Everything is migrated to the new server and I am trying to unistall Exchange 2010 on the old server, when trying, I get the following error:

An error occurred while running the test. The computer may be out of memory, or the XML files have been modified.
 Parameter name: ConfigurationFileLocation

Also in Exchange Shell I run the following: Test-SystemHealth
And I get the same error.
 
Can someone help me?
