I'm not sure what issue you're running into specifically, but I know of one:
Some time after Mac OS X 10.6 Snow Leopard, Apple changed Migration Assistant
so that any migrated users "helpfully" have their home directories moved into
/Users/. This breaks those users, if those users were created by MacPorts or
its installer, since those users need to have their home directories where we
put them. Undoing this undesired "helpfulness" is nontrivial because *for each
affected user* you need to identify what the correct home directory is, move
the home directory back there, and use dscl to fix its directory services entry.
This may be MacPorts' fault for creating users with UIDs >= 500. It is possible
that if we created UIDs < 500 the migration assistant would not do this to
them. It is worth testing. However, see https://trac.macports.org/ticket/11596
where it is stated that UIDs < 500 are reserved by Apple. I don't know if that
was true then or if it is still the case now.

Apologies if we've already covered this in another thread, I don't remember,
but you should have no difficulty locating the last compatible version of Xcode
for any version of macOS by consulting
https://trac.macports.org/wiki/XcodeVersionInfo and downloading it from
https://developer.apple.com/download/more/?=Xcode
I see that unfortunately our guide at
https://guide.macports.org/#installing.xcode says "Download the latest version
of Xcode" while neglecting to add "that is compatible with your version of
macOS". We should update the guide.

In general that has not been my experience. I often find the answers I need at
the Stack Overflow family of sites.
