AFAIR you will have to perform full reinstall when upgrading to Q4 because of switch to LVM.
I am in similar situation. I plan buying a new laptop, because my current laptop EOLs soon (end of 5Y warranty). I cannot migrate to Qubes 4 before that (compatibility issues) and I don't want to install 3.2 on the new laptop and perform full reinstall in few weeks/months.
