Database Migration Explained - What is It & How to Migrate?

What is database migration and how to best migrate your database management system to another DBMS or server?
This database migration explained video will walk you through what sql database migration is, what database migration types are, and how everything works.

Migrating a database or a DBMS is like restructuring a building.
For the database migration process to complete successfully, you need a plan to not overlook anything that's necessary for the database to work properly.
Plan your migration to ensure efficiency, data integrity, and a smooth transition process.

Before migrating your database, you first need to decide what type of database migration you're after.
The two most common types of database migration are data migration and database schema migration.
Think of data migration as moving the things in a building such as the furniture and the like, while schema migration can be thought of as migrating the blueprint or the core foundation of the house itself.
There are different things you should consider when migrating your data, your schema, or both of those things, so having a goal of what you want to achieve when migrating is a crucial step in your journey.

When migrating data in your database management system, you may be transferring data from one database system to another, upgrading the version of your database, or changing the way your data is stored or accessed.
When migrating the schema, you may be changing the data types of specific columns, introducing, changing or removing sql indexes or partitions, or adding, altering, or dropping tables.

No matter which type of database migration you're after, this database migration explained video will tell you that you should keep in mind that if you're migrating to a different DBMS, some of the things you're used to might change.
Configuration may be different, database schemas may change, and other functionality you're used to may not be available, so it's crucial to keep yourself educated about both types of database management systems you find yourself using. Documentation is a life-saver in that regard.

Keep an eye on your database backup strategy and make sure your sql database backups can be restored too - your sql backup type will directly impact the database migration process.

The size of data also has a direct impact on the database backup and restoration process. The bigger your data set is, the longer it will take to be restored, so instead of making logical database backups, consider exporting the raw data itself and re-importing it as necessary.

Various database management systems have various options related to this, such as MySQL Server's LOAD DATA INFILE SQL queries and the like, so look around and you'll definitely find something that fits your use case when migrating your database instance.
