I have a MacBook Pro 2017 15” Touch Bar.
I was wondering if I could replace the current logic board that I have with a 32GB RAM one from an 2018 MacBook Pro? I am asking so I can upgrade in 3-5 years’ time in case this one gets old.
Es esta una buena pregunta?

Replacing the RAM or Flash chips on this logic board requires very specialized equipment and not a DIY'er job. The T2 chip does not deal with the RAM only the Flash (the T2 is only in the 2018 models). Apple uses custom RAM & Flash chips which are not available on the open market at this time, so thats not really an option.
Swapping out the logic board is the only alternative and Apple charges a premium and only permits a direct swap-out (same sized bd). Thus, leaving you to locate a used logic board which will also go for a very high cost and thats is assuming it could be done at all. I'm sure no one has even attempted this given how new the system is

Sadly, It would be more expensive than just buying a new system.

@ronnham “I am asking so I can upgrade in 3-5 years’ time in case this one gets old. “ since you are dealing with Apple we really do not know if it will work in a few years. This company has a tendency of throwing monkey wrenches in updates/upgrades and DIY’er. You’ll already have to modify it now so I would imagine that in 3-5 years it will not be any easier :-)

Wow, the response on this is amazing. I think this answers my question :)
I was just wondering if the 2018 model logic board would fit into my 2017 model chassis, given that the 2018 model has a slightly larger battery… etc. I’m happy to do it myself, and I’m sure I’d be able to find a logic board with 32gb ram in a few years’ time when the upgrade is due…
I’m aiming to do the same thing with my backup mid-2014 MacBook Air, I found a relatively cheap i7 8gb ram logicboard to swap my current i5 4gb ram one with :)

I think your over reaching as no one has even attempted this. Don't forget the '18 model has a better keyboard. Come back in a year or two and ask the question then.
