A lot of engineering work has gone into easing upgrades for SQL Server and Windows at Microsoft. In general, a lot of breaking changes no longer happen especially around the database engine. But what about other components? What about Windows?
Many folks are wondering where to get the documents to help guide them on software upgrades.
I compiled a few links for a support manager in Microsoft, and am sharing them here. I think this will help you get started.
