Best practices and benchmarking

This section provides our best information about how to speed up and simplify your migration, and provides guidance about how much time you can expect migration to require.

Best practices and recommendations

• Migrate data from a replicated Magento 1 database instance
• Remove outdated and redundant data from your Magento 1 database (for example, you could remove logs, order quotes, recently viewed or compared products, visitors, event-specific categories, promotional rules, and so on)
• To avoid any unexpected issues or conflicts please follow steps described in General Rules for Successful Migration
• To boost performance you can set <direct_document_copy>1</direct_document_copy> option in your config.xml. In this case, Magento 1 and Magento 2 databases should be located in one MySQL instance, and the database account must access each database

Benchmarking estimates

We tested migration on the following system:

• Environment: Virtual Box VM, CentOS 6, 2.5Gb RAM, CPU 1 core 2.6GHz
• Database had 177k products, 355k orders, 214k customers

Performance Results

• Settings migration time: ~10 mins
• Data migration time: ~9 hrs (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
