502<title>Updating Portage to Support Cascading Profiles</title>

506Although this section does not seem to integrate well in this upgrading guide,
507it is quite important. Any profile listed above this section requires a Portage
508version that supports cascading profiles. However, some obsoleted profiles don't
509allow the user to upgrade Portage or the user is using a profile that isn't
510available anymore - any attempt to upgrade Portage will result in a failure.
511</p>

514To work around this problem, users can set a temporary symbolic link to the
515<e>obsolete</e> profile, allowing them to upgrade their Portage after which
516they can continue with the upgrade procedure set forth in this guide:
