2) The biggest drawback to separation after years of service is that customers have come to expect their DNS changes are propagated instantly when they are on-net. This turns out to be more of an annoyance to us than our customers, since our zone is probably the most frequently updated.
If you're running bind for your recursive boxes, `rndc -s <server> flushname <zone>' run against each recursive box should do the trick for bind 9.3.0 upwards. It will flush the cache for that zone only. There was a bug where it wouldn't flush negative caches, but that might be fixed. YMMV, etc.
Usual common sense warnings apply.
