How did you get your dream lateral?

Hey fellow wso'ers I have asked this question already on the boards but have yet to truly find someone whose brain I can pick about this. I want to lateral from a MM bank to a top M&A or industry group at a top BB or elite boutique in NYC. Not really just for the exit opps but for the high profile deals, the big city, and yes the exit opps SHOULD I decide I want to switch later in life.

I have used the search fiction extensively but the info is old and the posters have been unreachable. Can someone who successfully lateraled from a mm bank to a top BB or elite boutique please PM me if you are willing to share insight and generally educate me on the process and your experience?

Thank you all for your help.
