Need to change a clients hosting provider and although I have done this on a number of occasions, this one I'm a little un-sure of.
They have 4 domains, 3 pointing to one of them, and one mail for all emails.
They want to swap to someone else server and some of the things within the email request i havent come accross before.
1st: they need us to email them a copy of the current zone file
(looked it up but not too sure what this means and how we do it)
2nd: they have a .org domain as part of the transfer and the new server company says whilst they cannot hold the 'Tag' for .org domains, they can still be authoritive for the DNS
(what does this mean?)
I understand that a site goes down for between 24-72 hrs when changing DNS and if Im right this is why they want a copy of the current file zone, but if so what are steps I need to take to get this done without hiccups?
thanks for any help

the internet provider security (IPS) tag is used by registrars to control domains and these must be changed by the original registrar to transfer domains to another registrar.
the registrar does not have to be the same organization as the DNS provider and in best practice probably shouldn't be.
you should configure the new domain name servers with the edited zone file and then change the name server records at your registrar so they point to the new name server addresses.
you should provide multiple domain name servers and they should be on different class C addresses.
this is so that there is not a single point of failure for your DNS.
when you are specifying multiple DNS, you must specify that one of them is the authoritative server.
this specification is done at the registrar and is also indicated in the zone file by using a server of authority (SOA) record.
when you are all done you should run a dns report to make sure everything is set up correctly and using best practices.
Not sure why the site goes down just because you're switching servers...
Is that wrong?
