 I've updated macOS from Sonoma 14.6 to Sequoia 15.0.
 Now I'm trying to update MacPorts and am following the instructions on
 wiki:Migration

 This does not work for me, I get an error message in the first call of
 `port`:

 {{{
 > sudo port migrate
 Error: Current platform "darwin 24" does not match expected platform
 "darwin 23"
 Error: If you upgraded your OS, please 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
 }}}

 Does this occur because I'm still on MacPorts 2.9.3 instead of 2.10.1?

 Is there a way to proceed with the migration or should I just remove the
 current installation and restart from scratch by installing the Sequoia
 version?

 Thanks

 First download and run the MacPorts installer for Sequoia from our web
 site.
