Before moving hosting, need to ask old provider change ns records?

Moving to another provider steps

I was sure about how to move from one hosting provider to another since I've done many times. But last time I faced a problem:

After some days from I delegated dns in proper nic, still couldn't resolve to the new hosting. Emails were entering in old provider and new one alternatively, that was a mess...

Asked new hosting about it, and they did [dnsreport.com...]

It was clear that my dns were pointing to my new hosting provider but all other data to old provider...

So they made me ask to my OLD provider to update that info.
That was a risk but they did and problem solved.

I wonder what would happen if old provider refuses, since I'm leaving their service (of course it's my right to decide what hosting to use but what if they don't?)

Is that necessary? All other times never did ask anything to the hosting I was leaving and worked right...

If your old host doesn't remove the site and entry from their internal DNS, anyone who accesses the 'net from their services will still go to the old site.

A classic case is someone would switch domain hosting and not tell us. So anyone using our Internet services who connected to the site would still get the old site. The internal DNS says "here it is right here, no need to query an external nameserver for it." This can persist for quite some time until the internal DNS gets updated.

So it's necessary to tell old hosting they change it.
If you don't is that updated in anyway alone by time?
