Moving your relationship to the "next" (higher) level: from friends to "friends with benefits" or dating; from dating to exclusive, from exclusive to moving in, etc. Sometimes the relationship upgrade requires considerable work from one partner to overcome the fears, worries, or hesitance of the other partner.
Person 1: I'm tired of being just friends with benefits. We need a relationship upgrade!
Person 2: What you want from me bro? I don't wanna be monogamous yet.
Person 1: Let's just date - some romance with our sex.
Person 2: Ok. I guess that's a cool relationship upgrade.

Someone socially upgrades when after being single, especially for a long time, gets involved in a serious relationship or marries. They stop hanging with the old crew because they now spend time with other couples only.

Keep in mind, this is a broad term that encompasses anyone from the guy who you used to chill with A LOT and now you don't see AT ALL, to someone you still chill with, but they treat you differently because they're with someone and you're not.
