Townsend will be looking to continue the form that has seen the Warriors finish in the top four twice in the last three years and Munro insists the former Scotland centre will be making minor adjustments rather than full-scale changes at Scotstoun.
Munro told the Scotsman: "One of the things we've tried to create over the past nine years is a Glasgow Warriors culture around how we work and how the club is perceived on and off the field.
"On the pitch the priority was making us a very tough team to beat, stemming from the defence. Obviously, we have worked on a good attack and strong set-piece, but from my perspective it's the traits of working hard for each other, respecting each other, players and coaches, and that no-one can expect to beat us anymore that everything now starts from.
"So, Gregor has come into a set-up that already has that ethos and a confidence from it, where everyone knows what we stand for, rather than us all sitting back and waiting to see how Gregor does things.
"He's a great character and coach, and has a lot of ideas, and we talk regularly about what kind of rugby we want to strive towards, but it's not going to be hugely different to what supporters have been used to seeing, just with a few little new things here and there."
