MWS 7.1.2 and monitor 6.5

We currently have fabric 7 installed. We made the broker upgrade to version 7.1.2 and it works fine. We now would like to upgrade MWS 7.0 to version 7.1.2 before upgrading the IS to version 7.1.2 (we currently have version 6.5).
I know it is not supported, but will this solution work or not? Can MWS 7.1.2 work with IS Monitor 6.5 or not?

If its not supported then it REALLY isnt suggested to do it. I mean, you CAN do it but as soon as you have an issue you are out on your own and Software AG support dont have to help you.
