As the majority of webmasters, in fact, is a group of vulnerable people, when we pay for it, IDC is what it says, the individual is basically powerless. As a result, changing web hosts has become the most common problem among webmasters and bloggers. The following is a list of techniques to migrate your website from one host to another under the same domain name to avoid unnecessary losses due to migration.
1: Prepare for the change of web hosting - Checking
The first thing you should do is to check if the web host you are replacing is secure, if it is blocked by search engines, and if there are any illegal websites on it, and never migrate your website to an unsafe and unreliable host.
2: Migrate your website during the time when the number of visitors is low
Generally, choosing the early morning hours is the best time to migrate a website. But it's impractical for people like me who can't stay up late, so getting up early to change spaces is best, like 7am. 2-5 p.m. and 8-11 p.m. is the peak time for Internet access, but also the most visited moments of the various websites, look at your statistics will be clear.
3: Make backups of your website
Backing up the database and uploading folders is most important, remember to always back up. If you don't know the directory structure of your website program, take the extra time to back up the entire site. Usually the backup is done by downloading these important directories to my computer. While making a backup of your website, you can first turn off the various services on your website, such as the comment and message functions.
4: Be sure to keep the original web hosting site
Use FTP to migrate to the new web host and manually verify if the website can be accessed normally. If the test is OK, start resolving the domain name from new.
5:The following is a list of some of the most important things you can do with your domain name
Domain name resolution setting method: member login → domain name management → click on the domain name that needs to be resolved → domain name resolution service → set up a new resolution address, that is, to modify the domain name's A record. In the domain control panel after the resolution of the domain name and quickly to the website control panel in the domain name from the new settings, generally two hours can successfully access the new web hosting.
6: Please keep the original website for at least 7 days.
The reason is that many search engines will cache the DNS, so if you delete all the data on the original site, there may be a large number of 404 error pages, and after the search engine cache DNS update, you can delete all the data on the original virtual space.
This is the end of the web hosting site migration work, in fact, it is very simple, remember: to ensure that two identical websites can appear at the same time in two different domains and normal access, and then domain resolution to the new site, and keep the old site for a period of time, focus on these steps.
