A1502 Logic board compatibility between 2014 and 2015

So I'm currently shopping for a new logic board for my dead mid-2014 macbook pro 13. I believe its an issue with the power regulation circuit meaning it is something I am not at all able to fix myself, so I figured I should get a new logic board and perhaps do an upgrade in the process. This is the exact one I have: https://everymac.com/systems/apple/macbo...

Firstly, can I put an i7 board into the case when it had an i5 in it previously?

When I'm searching ebay for "A1502 logic board i7" I get 2014 and 2015 models. Will a 2015 logic board work with the rest of my 2014 hardware, assuming both are 'A1502'?

Additionally, if I put my old SSD in the new board do I need to do any sort of formatting to get it to run properly or should it just work from the get go?

Thanks!
