[cisco-voip] BE5K to BE6K upgrade

[Brian Meade]

Russell,

Transfering and conferencing will work fine.  You'll only have issues with
secure services such as corporate directory.  If both clusters are going to
be up at the same time, I'd really suggest doing the Bulk Certificate
Export/Consolidate/Import method instead of the rollback method.  That way
your users won't lose any features prior to the migration.
