transferring website and emails to new provider
We are moving 2 websites to hostpoint.
We just moved the first domain.
Domain name by registrar infomaniak.ch
Old provider green.ch
New provider hostpoint.ch
Now, the problem is that, apparently, it takes much longer for the servers to change the MX-records than the DNS records.
Any advise how to better synchronize the 2 parts of the transfer (MX (email servers) and DNS (web servers)?
My idea would be to change the MX-Records first and once it is done, then change the DNS records.
I am not sure though where to request the change of the MX-Records?
By the domain name registrar (Infomaniak)?
Or by the old web provider (green.ch)?
Thank you for your inputs.
