DNS cache flushing and quicker DNS zone transfer

Our organization is on the verge of changing over IP addresses for the network. What I need to know is:

1. Is there a way to flush the DNS cache from the NS that has been tried and verified?

2. Is there a way to force DNS zone transfers from the servers as to update the local NS in a more timely manner?

Re: DNS cache flushing and quicker DNS zone transfer

What you need to do is change the SOA record for the DNS zone and use a very small TTL. You have to do it a couple of days before your actual address change. This will ensure that all other DNS servers will cache the information for a very short time only and any change on the primary will quickly reflect to other DNS servers.

Am I wrong, or is this a double-post? Please see response to other post.
