I have a FreeIPA 1.2.1 system (1 master and 1 replica server) running
on Fedora 14. I'd like to migrate to FreeIPA 2, now that Fedora 15 has
been released. But I have a few questions:

1. Can Fedora 15 clients authenticate against my FreeIPA 1 servers?

Yes but you would have to configure it yourself. sssd would work nicely with an ldap/krb5 configuration.

2. Can Fedora 14 (and older, and Windows and Mac) clients authenticate
against FreeIPA 2 servers?

You would need to either build your own Fedora 14 ipa-client v2 package or manually configure it. The sssd in F-14 should work well even using the ipa provider.

Windows domain login is not supported.

3. Can I migrate the servers from FreeIPA 1 to 2 (presumably requiring
an upgrade from Fedora 14 to 15 along the way).

You cannot do a straight upgrade, too much changed between the two versions. You should be able to migrate the users and groups using the v2 migration system. This will maintain your user passwords at least. You would need to generate new principals and keytabs for your kerberized services.

I don't think it would be practical to try to run the two systems side-by-side.
