How to properly update python from py37 to py38

I have some jails that use a bunch of py37- packages. Is there some sort of elegant way to update them to py38- packages?

Or is it just possible to create a list of them, uninstall the old ones and install the new version?

  The default version of python3 and python was switched to 3.8.

  For ports users wanting to keep version 3.7 as default,
  add DEFAULT_VERSIONS+= python=3.7 python3=3.7 to make.conf

  Following procedures may ease the upgrade:

  For users of pre-build packages:
  # sh
  # for i in $(pkg query -g %n 'py37-*'); do pkg set -yn ${i}:py38-${i#py37-}; done
  # pkg upgrade

  For portmaster users:
  # sh
  # portmaster -o lang/python38 python37
  # REINSTALL="$(pkg info -o "*py37*" | awk '{printf "%s ", $2}')"
  # pkg delete -f "*py37*"
  # portmaster $REINSTALL
  # REBUILD=$(pkg query -g "%n:%dn" '*' | grep py3 | grep -v py38 | cut -d : -f 1 | sort -u)
  # portmaster $REBUILD
  # REBUILD2=$(pkg list | grep python-37 | xargs pkg which | awk '{print $6}' | sort -u)
  # portmaster $REBUILD2
