Domain and mail transfer from Nic.ru. Do I understand correctly?

Question

Domain name market

Good afternoon. Please guide me on what's going on. I'm doing everything for the first time, so I can't understand everything.

Now - there is a hosting with a domain on nic.ru. In the same place mail hangs on their own service.
It is planned - you need to transfer hosting and domain to reg.ru, and pick up mail to Yandex / mail (have not decided yet)

With the transfer of hosting (or rather the site), I had no questions. Domain transfer - this is where the questions begin. As far as I understand, based on unsubstantiated logic, everything will be like this:

1. The domain moves to reg.ru with all the old dns records that link to nic.ru, and in theory, hosting and mail should continue to work for the time being from the rucenter .
2. To the domain already on reg.ru, I cling Yandex / mail mail and set up migration - mailboxes and all mail are transferred, and all the new mail is collected to the heap (is it completed?), Which so far comes to nic.ru. A box with new mail is connected on users' devices and they go to it.
3. I edit dns and prescribe records already for reg.ru and mail service. Nothing else links to nic.ru, the site works with reg.ru, all mail comes directly to Yandex / mail, bypassing the rucenter. On users' devices, I delete old rucenter accounts.

It's like that? Or am I thus slowing down the work of the office for a couple of days or more?

Answer 1

First, transfer the mail to the traffic rules. and therefore already change hosting.
Yandex traffic rules have mail import.
I don’t know about mailra - I don’t use it, but I think that it should also be.

Answer 2

There are no days, more hours.
Decide who you'll pay for the domain. If you want everything to be through reg.ru, then:
1. You move the domain from nickname ru to reg ru, the process takes up to 4 hours
2. Mail records will also move to roar, so in the dns settings change MX to the third-party service you have chosen ( yandex, etc.)
3. One of the ways to get mail is guaranteed:
3.1 you wait and DO NOT set up a new mailer for users in clients for several hours, until you are sure that all letters go through new routes
3.2 Only after you have made sure that everything goes as it is necessary, change the settings in all clients to a new one.
From experience, in the morning, while coffee is being brewed, dns moves, by 10 o'clock all the caches have already been updated, the office is working normally. You set up each new employee who comes to work)

Answer 3

Do not understand correctly, the domain must be hosted separately either in reg.ru, or in pdd or in biz. In fact, you now have three different services - domain registration, DNS zone hosting and mail hosting, they can all be independently operated by different parties and they are all transferable.
1. Lower the TTL in the DNS zone to a few minutes
2. Create a copy of your DNS zone in pdd or on biz or on reg.ru if you will use their DNS zone hosting service
3. Change the DNS servers in the new zone
4. Change DNS servers at the registrar (nic, ru)
5. Validate the zone (in case of biz)
6. Transfer mail to pdd or biz - in principle, you can do this at earlier steps, but it is more likely to get interruptions
7. Rearrange MXs with nic .ru on pdd or biz
8. Transfer zone from nic.ru to reg.ru
9. Restore normal TTL values
