You can now create and use a configuration template to set up your environment for optimal performance when you migrate application data. Correctly setting up your environment helps ensure a successful migration. From the new Migration settings landing page, you can configure and save the following options that might affect data migration performance.

• History – disable history for all classes.
• Database indexing and background processing – turn off database indexing, auto vacuuming, and background processing for database tables with which the migration interacts.
• Queue processors, agents, job schedulers, and listeners – turn off processes that are not required for migration so that the resources are free and do not interrupt the migration process.
• Dynamic system settings that apply to data migration.

After you have finished migrating data, you can revert your system to its normal working state.

A guardrail warning has been added to the import wizard that warns you when the operator doing the import has Allow rule checkout enabled. The Allow rule checkout option might affect performance; therefore, it is recommended that you disable this option or use an operator ID that does not have this option enabled.
