What is Hosting Migration?

Hosting migration is the process of transferring a website's complete infrastructure from one hosting environment to another. This includes the website files, database content, email accounts, SSL certificates, DNS records, cron jobs, and any server-specific configuration.

Why migrations happen

The most common reasons are performance problems on the current host, a pricing change, the need for more server resources (upgrading from shared to VPS), or dissatisfaction with support quality. Sometimes it's simply that a better option has become available.

What can go wrong

Migration failures typically fall into three categories: data loss (files or database rows not transferred), configuration drift (the new server has different PHP versions, disabled functions, or different path structures), and DNS timing errors (going live on the new server before DNS has fully propagated, causing some users to reach the old server and others the new one simultaneously).

The buffer period

The single most important migration practice that most guides omit: keep your old hosting account active for at least 30 days after going live on the new host. DNS propagation can take 48–72 hours for some ISP resolvers. Some users will still be hitting your old server days after you switched. Cancelling the old account prematurely leaves those users reaching a dead server with no content.
