It will help to know what the panic is, even just a short title, and
how far it got into the boot sequence, as well as what your starting
point is (13.x, 14.x etc).

Did you also update the boot loader (whether UEFI or MBR ? ) on all
drives?

BTW I highly recommend beinstall.sh  ( /usr/src/tools/build/beinstall.sh )
which creates a zfs boot environment from your existing system, builds
src as you'd usually do, and then installs into the new boot env. So
long as you keep the main boot loader updated, this is a very very nice
setup. You can select boot environments in the loader prompt and switch
quickly between working & not. This may require some alignment with your
multi pool setup of course.
