I would like to repeat that upgrading MacPorts from the 'port migrate'
action is not possible. After a major upgrade of macOS we cannot
guarantee that the old version of MacPorts runs at all on this new OS
version. MacPorts has to be reinstalled for the new OS version in an
extra step before.

The best you can do is printing instructions on where to download MacPorts.
