How to migrate a MySQL server database from an older version to a newer?

All we need is an easy explanation of the problem, so here it is.

I am trying to import a database from an older MySQL server (v 5.0) to a newer (8.0).

So I exported the dump file from the original database, and tried to import in the newer system, but then it’s showing a thousand syntax errors.

The thing is that the older database is working fine, so I presume that the problem is the version. May someone help? Thanks!

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Unfortunately, I do not have old databases to test this with, but for migrations of this type in the past (MySQL 4.x ~ 5.7), I had to follow this process:

  1. Create a dump of the database and import it onto another machine, either using the same version or just slightly newer (for example, build a VM or Docker container with MySQL 5.0~5.2 and import)
  2. Upgrade the MySQL installation to the next major point release
  3. Repeat step 2 until you’re at a more recent, target-compatible version
  4. Dump the database
  5. Import into the target version
  6. Test, test, test, and test

That last point is really important 🤐

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
