Data migration best practices

This section provides best recommendations to accelerate and simplify your migration and guidance about how much time it may take.

Use a copy of the database from a Magento 1 instance when performing migration testing. Do not use the production instance of your Magento 1 store database.
Remove outdated and redundant data from your Magento 1 database before migration.

Such data may include logs, order quotes, recently viewed or compared products, visitors, event-specific categories, and promotional rules.

Follow the general rules for successful migration.
To boost performance, enable the direct_document_copy option in your config.xml file:
```
<direct_document_copy>1</direct_document_copy>
```

NOTE

Both Magento 1 and Magento 2 databases must be located on the same MySQL server and the database account must have access to both databases.

Benchmarking estimates

Adobe has tested data migration on the following system:

Settings migration time: ~10 minutes
Data migration time: ~9 hours (all data except URL rewrites, ~85% of total data)
Site downtime estimate: a few minutes to reindex and change DNS settings. Additional time required to warm up the page cache.
