Upgrading from Heimdal 0.4 to 0.6

[Chris Schadl]

Apologies in advance if this is off-topic.

I'm going to be upgrading my kerberos clients and KDC from heimdal version
0.4e to 0.6.2.  I was wondering if I will need to do anyting like
re-create or modify my existing principals created under 0.4, and I was
also wondering if the 0.6.2 clients (which will be the first to be
upgraded) will still be able to authenticate against the 0.4e KDC during
the transition period.

Thanks,

Chris Schadl
