Deb,

Make sure you reduce the TTL (Time to live) on the DNS records some time
before you update the DNS records. Otherwise, some DNS servers and
clients may have the old IP address cached. Reducing the TTL increases
the load on your DNS servers because the record will be checked more
frequently, but it will minimize the caching issue.

Hello All!

Happy Holidays!  We are considering changing IP addresses on the CCA
servers and/or managers.  I cannot identify any potential problems- my
certs are tied to domain name- servers connect through the shared
secret.  Does anyone know of any hidden "gotchas" here?

Thanks!
