Upgrade report for 1.7 to 2.x

I am happy to report that with a few fixes, I was able to upgrade my home installation from 1.7 to the current 2.x Debian packages.

Awesome!

It's actually pretty painful - i had to:

  1. package Drush 5
  2. fixup the Aegir Debian packages
  3. run the hostmaster upgrade twice, as it failed because of the drush commandfile cache (fixed in hostmaster-migrate by running drush @hostmaster cache-clear drush after the upgrade)
  4. run drush @hostmaster hosting-setup to reinstall the crontab, probably because of the failure in the last step
  5. remove the provisionacl module which needs to be ported.
  6. disable the hosting-queue runner (it also needs to be ported, see #1189556)
