So far as I can recall, raw zone file format hasn't changed. Journal file format did change once, but the change should be detected and handled correctly when upgrading, and there's a tool for upgrading or downgrading manually if needed (named-journalprint -u and -d, respectively). There was also a "map" file format for a while, and it was much touchier, but it's been removed now. -- Evan Hunt -- e...@isc.org Internet Systems Consortium, Inc. -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
