The normal upgrade, and hence tested, procedure is older clients and 
newer server, IOW upgrade servers first and then the clients. See [1]

As a result, we would not be able to provide guidance on the request. 
Further 3.7 is EOL for some time now, so issues that appear may also not 
get enough attention or suggestions.
