What is the method of website migration to replace the server? I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The method of website migration and server replacement

1. Website backup

Website backup is database backup. Before replacing a new server, the webmaster first downloads all the data on the old server locally. If you don't know how to download it, you can ask for help on the space.

2. Modify the cache time of DNS server

Here we will refer to a concept of time to live, which is abbreviated to TTL, which refers to the retention time recorded in the DNS server every month. When replacing a new server for a website, the webmaster should set the DNS TTL value as low as possible, which can speed up the effective time of domain name resolution and facilitate the website that the search engine refers to as soon as possible. Otherwise, spiders may not be able to crawl the site.

3. Upload the data to the new server and complete the parsing

The webmaster needs to upload the pre-backed up website data to the new server, and then check whether the website can be accessed, whether the database is missing, whether the background can be opened, and if there is no problem, you can resolve the website domain name to the new server. At this point, it is important to note that the Web site on the old server must remain running while doing all of the above. As long as to ensure that user access, spider crawling are normal, the ranking of the site will not be affected by the replacement of the server fluctuations.

4. Pay close attention to the IIS log to see if the spider crawls the website

The webmaster should also pay attention to the IIS log of the new server, mainly to see whether the spider begins to crawl the data on the new server. Once a normal spider crawl record is generated, it shows that the replacement of the server has been more than half successful. Because domain name resolution will not be fully resolved to the replacement server within 72 hours, the data of the old server should remain unchanged during the resolution period.

5. Two servers run for 1 to 2 days

It is recommended to keep it for 1 to 2 days, and then shut down the old server after the site is running steadily on the new server. This will help you ensure that you will not lose any access to users or emails. Search engines also tend to update DNS records every 24 hours or less. Therefore, even if the search engine can handle this kind of site migration, DNS records, just in case, it is recommended that the new and old servers keep transitional search engine updates for a day or two.

6. Update content and release chain

After the replacement, Baidu has a new review period for the site, we should improve the quality of the article and try to adopt the original way. After the update, send out the chain to attract spiders. For example, go to popular forums or blog outside the chain, lead it into the site, this process takes a period of time, need to adhere to.

7. Delete old server data

After the website runs stably, the webmaster can delete the old server data, and the website here can be regarded as a successful migration.
