I "feel your pain". We moved about three years ago, twice. We sold our house immediately in early 2020 and our new home wasn't ready until around Thanksgiving that year.
In my case I kept all the original boxes and with help from my son & friends, boxed all the components up and moved them to a climate controlled storage unit, part of "decluttering" our former home.
When the movers came to deliver our stuff to the new home, they carried all that heavy stuff up the 15 steps to my bonus room. My son helped me unbox and setup the system in its new, and permanent home!
Good luck with the move. I'm not doing that again!
