Webmethods upgrade 7.1 to 8.2 and OS migration

Hello

I’m new to webMethods and working on a migration / upgrade project.

Does anyone have experience of migrating the Operating system from Unix to Windows as well as upgrading
webMethods from 7.1.3 to 8.2?

What would be the preferred upgrade path? OS, followed by webMethods or vice versa?

Thanks in advance
Jonty

Please refer to upgrade document available in Empower, there is detail steps about upgrade from 7.1.x to 8.2
