Error upgrading to macport 10.0

[Raoul MEGELAS]

	hello,

It is bizarre!
Here is what I get:
Error: Current platform "darwin 23" does not match expected platform "darwin 23"
Error: Please run 'sudo port migrate' or follow the migration instructions: https://trac.macports.org/wiki/Migration
OS platform mismatch
    while executing
"mportinit ui_options global_options global_variations"
Error: /opt/local/bin/port: Failed to initialize MacPorts, OS platform mismatch

What to do now?
Thanks and bests.
