BIND 4 to BIND 9 Migration Notes
@ -48,3 +48,9 @@ ignoring the DNSSEC records (SIG, NXT, KEY) that BIND 4 did not support.
BIND 9 is less tolerant of errors in master files, so check your logs and
fix any errors reported. The named-checkzone program can also be to check
master files.
Outgoing zone transfers now use the "many-answers" format by default.
This format is not understood by certain old versions of BIND 4.
You can work around this problem using the option "transfer-format
one-answer;", but since these old versions all have known security
problems, the correct fix is to upgrade the slave servers.
