Upgrade MWS or NOT to v8.2

I’m performing a side-by-side upgrade from v7.1.2 to v8.2. I was going to perform fresh installation of IS, Broker, and TN. I also have MWS v7.1.2 running and debating if it’s necessary to perform a fresh install of MWS or not. Is it really necessary?

There is a section steps for Before Upgrading Monitor and Before Upgrading My webMethods Server and then you would need 8.2 install anyways . please check it:
