Shifting database from one server to another

Question

We are working on the CRM site. Now we have to shift the site from one server to another server. We are not having the problem for shifting the files since we are working on that so we know the changes or update in those files. But we have to shift the DB from one server to another server without losing a single data.We planned to make access the old server DB from the new server still we are changing the DB from old server to new server. But the problem is when we are doing this process the user have the possibilities to inserting the records to old DB. So we lose those data since we already taken the DUMP.So kindly suggest us what is the best way to doing the DB transfer with losing single data.

we are thinking to take the records between the times from dumping to changing to new server. Is that possible?.... if yes kindly suggest us how?...

Answer 1

Allow updates from both servers, that is, the old DB server will take updates. When the DNS migration is finished, only then migrate the DB data. Still, there's likely to be some downtime, but scripts can speed this up.
