Preconditions
Before starting migration, make sure the following requirements are met.
Magento 2 system
-
Set up your Magento 2 system so that it meets the system requirements.
Use a topology and design that at least matches your existing Magento 1 system.
Cron
Do not start Magento 2 cron jobs.
Database
-
After installation, back up or dump your Magento 2 database as soon as possible. This allows you to restore the initial database state if migration is not successful.
-
Verify if the Data Migration Tool has network access to connect the Magento 1 and Magento 2 databases.
Open ports in your firewall so that the Migration Tool can communicate with the databases.
-
Make sure your MySQL accounts have all the necessary privileges to access Magento databases.
If Binary Logging is enabled for your Magento 1 database, set the global log_bin_trust_function_creators MySQL system variable to 1, or grant the SUPER privilege to your account.
- We do not recommend creating new entities (products, categories, attributes, etc.) in your Magento 2 store before migration because the Data Migration Tool overwrites such new entities with the old ones from Magento 1.
Extensions
Migrate Magento 1 extension code to Magento 2.
To find the latest extensions versions, visit Magento Marketplace or contact your extension provider.
You can also use the Magento Code Migration Tool.
