IP rep is a big deal, still. You might want to keep the existing IP. Or if you do plan to keep it, relay mail from your new server through it.
SMB/low volume mail is the trickiest to sort of IP warm correctly, so I honestly expect you'll have some pain. Here and elsewhere you'll find people complaining that Gmail is completely unfair to the small volume sender. Sounds like you're smarter than most, but it's still tricky, both with Gmail and Microsoft. I'm having similar concerns myself, as I move a lot of what I do into AWS, I don't want to lose the sending reputation of my legacy hosted server that I've had for years, so I'm going to keep it, basically just as a mail relay.
