Websites need to replace the server should be how to do?

Generally when we first started building websites, the site required flow or space estimates are not particularly understand, there may be like renting server performance can't satisfy the demand, so we will need to extend the late server configuration or replace better server, in either case, must consider the problem is the website needs to be prepared to what the server to transfer,
The first is on the choice of server
When choosing transfer server need to determine whether the transfer to the new server can meet the demand, generally choose server mainly from server access speed, stability, security, after-sales service and so on into consideration, we can find several service providers to test server performance, choose the best of the best,
Followed by all of the web site data backup
Server transfer, before we shift in server, do a full backup, including database and all the procedures, page, image, etc., in case of other data in the process of transfer happen and cause data loss problem,
And then the test server can run normally
In order to prevent the transfer after the server has the other situation, we need before the site data transfer, to test the new server, you need to backup beforehand good website data uploaded to the new server, and then check if site can access, database without missing, can open the background? If no problem, you can put the website domain name resolution to the new server, it should be noted that the new server check above, on the old server site also best running condition, as long as the guarantee user access, spiders are normal, the site's ranking is not affected by the replacement server change, keep 1 to 2 days, wait until the website on the new server and stable operation, then shut off the old server, to prevent other conditions lead to the loss of customers,
Finally the note

Domestic now do website in accordance with the rules, in domestic, your server must be put on record, and the record must be performed by the service provider, if you transfer the server, the server providers, is likely to be off for the record, you need to put on record,
