Re: Changing ISP, updating DNSFrom: clyde Date: Friday, March 10, 2000
Time: 4:01:00 amhi all,
I'm about to switch isps. The old isp's line is up and the new isp's line is
also up. I search menandmice.com site for a howto on changing but didn't
find one...
From reading this thread of messages I've come up with this perliminary plan
to switch services from the old addresses to to the new addresses.
1. Change the ttl's for each domain down to 1 hour (3600) on the primary
name server. (which I did about an 6:30pm pst...)
2. I'll move the secondary dns server to the new network sometime in the
next day or too...
3. Update all the primary records to reflect the new secondary server...
4. Move the least used server (or service) to the new network connection and
update the primary dns pointing to it's new home.
5. Repeat 4 for each server.
6. When the last server on the old network is the primary DNS then I'll
setup a temporary dns server to act as a primary on the new network. Update
Internic records. And wait...
7. Once primary dns changes are reflected by Interic. Then shut down the old
network. move the old primary dns to the new network to replace the
temporary...
So. is this a reasonable course of action to pursue? Any pitfalls or
variations that make the switch over easier/better...
Thanks for any advice.
