This page describes how to move your data to an instance running a later version of MySQL.
The steps for moving your data from one version of MySQL to another involve exporting data from the current instance and importing that data into a new instance running the later version of MySQL. This process involves downtime; you put the current instance into read-only mode before starting the export.
Before you begin
Before moving your data to an instance running a newer version of MySQL, you should familiarize yourself with the differences between the MySQL versions:
To move your data to a Cloud SQL instance running a later version of MySQL:
Create the target instance, with the desired MySQL version.
Make sure the target instance has:
* The same user accounts, with the same MySQL privileges and passwords. For help with creating an instance, see [Creating an instance][creating]. Note: the target instance can be a Second Generation instance, even if the current instance is a First Generation instance.
Confirm that you can connect to the new instance with your local MySQL tools and update them if necessary.
Put your current Cloud SQL instance into read-only mode by setting the
read_onlydatabase flag to
For help, see Configuring Database Flags.
Export the current instance's data to a SQL dump file, following the instructions in Exporting data for Import into Cloud SQL.
Do not export the
Create a Cloud Storage bucket if needed, and upload your SQL dump file to the bucket.
Import the data to the target instance, following the instructions in Importing MySQL databases from Cloud Storage.
Update your applications to connect to the new instance.
When you are confident that your new instance is operating successfully, delete the old instance.
