Moving from West Coast IB --> East Coast IB

Hi All -

For some background, I am currently a 1st year Associate working at a BB in the SF bay area. I previously did 2 years in IB at a different bank in NYC, when I decided to say fuck it and adventure a bit and try out west coast (you only live once!). I am not interested in buy-side at this point. I (shockingly) really like banking, and could see myself in banking for a while, at least at this point.

I have lived in SF for almost a year now, and while I enjoy it here, I am thinking where I want to "settle down" soon-ish. I am an east coast person, and would like to be in NYC. I LOVE my group. I was wondering how realistic it is (keeping in mind that HR always touts mobility this mobility that) to actually move, ideally internally, from the west coast back to NYC. I would consider other groups/banks, but would much rather stay internally.

If anyone has any experience with this, or knows anyone that made this move, any context at all will be appreciated. And yes, I have used the search function, but the few threads I found did not have much actual context and a bunch of "bumps" or uninformative posts. Thanks all :)
