Following latest UPGRADE.txt (from CVS) ruined my Aegir frontend

Hi!

I had a clean Aegir setup. A new Drupal version was released. I asked at #aegir for a step by step guide to migrate sites to a new platform. I was told: 1) Create new platform; 2) Migrate; 3) Check and relax.

Okay... I created a new platform and tried to run a batch update on the old one. I saw that modules and themes were missing. So copied sites/all/* from the old platform to the new one.

The migration was performed flawlessly, but Aegir's site did not migrate.

I was told that i should follow UPDATE.txt to migrate Aegir itself.

Okay. I opened the latest UPDATE.txt in repo and updated the backend. But when updating the frontend i've had a problem.

The 'hostmaster migrate' drush command (performed on the old platform) gave a lot of warnings that Aegir features aren't supported on the new platform and will be disabled. Sorry, i lost the messages in my screen terminal. :(

The Aegir site didn't work anymore. I ran 'drush dl eldir hosting modalframe' on the new platform, enabled them in Aegir site and it was fixed again.

But i still have problems:
1) Aegir thinks he's installed on the old platform, not the new one.
2) Queue won't execute.

I'm stuck. Drush 'hostmaster migrate' won't run again because Aegir's site was removed from the old platform.
