It should be fine. I have signed domains that don't have dlv records (and parent doesn't know) and they work for others fine. > What do I do when I want to change to new keys?

If so, then changing the dlv record should be ok. Yes, keep both keys at same time.

Some do annnually. Some say several years is fine. (There were detailed postings about this recently on this list.) > What happens if one of our secondaries has no special setup for dnssec? > Should it be still able to serve any records that it gets in the zone > transfer? It will be able to serve them. But it won't return the RRSIG or DS records automatically (so no DNSSEC). > And if it does not serve the key records when there are dlv > records at isc.org what happens? Then it will be normal DNS. The DLV records won't be consulted (at least won't be required).
