I've transferred one domain to be pointed from host A to host B. It all went smooth enough. Now I'm going to transfer a domain from registrar 1 to registrar 2 but keep it aiming at the same host. So instead of the site's location moving I'm now moving the location of the domain, sort of. The current registrar mentions: "Transferring the domains out requires us to have the IPS tag for the person you are transferring to." Question is, as soon as we do this, what will happen? Will there be down-time or will nothing happen at all in terms of what the end user gets to see? Does stuff need to propagate or what? I look forward to hearing the low-down on this process...
I would think only the registrar tag would. Just send the request through and accept the request via the email they will send you. Process will take a few days...
If it's a .uk domain (which since we're talking IPS-KEYs it must be), the transfer is pretty damn quick nowadays. The process is slightly different than with .com's in that with .uk domains it is the outgoing registrar that initiates the transfer. The entire process can be completed in less that an hour, then you just need to wait for the cTLD zone file to propagate - so the change shows up in the whois. Name server entries shouldn't change, however, that will depend on who you're transferring the domain to. I know of a few ISPs/hosting companies in the UK that automatically change the nameserver entries on all domains transferred to them.
The site isn't moving hosts so why should the nameservers be affected? Anyway I spoke to both registrars now and they concurred what you guys said. The releasing registrar is the only one who can spoil the feast by 'blocking' the domain during the process apparently but besides such a calculated cock-up nothing will be affected as far as visitors are concerned.
One more thing though. Once the releasing registrar sets the domain to the receiving registar's IPS tag, do we have to inform the new registrar or do anything at all or will all magically transfer?
Once the "old" registrar releases the domain, It should "magically" appear in your account at the "new" registrar. Nothing further should be needed on your end.
