Best Practices Migration with PROC MIGRATE: Create Backups and Benchmarks

To execute a successful migration, start by creating backups and benchmarks as a safety net.

Step 1: Create an active or restorable backup image
By backing up your source installation before you modify any part of it, you ensure that you can reestablish the installation in a disaster-recovery situation. Planning for a worst-case scenario provides peace of mind during migration.

Step 2: Design a validation plan and create benchmarks
Benchmarks are "snapshots" of SAS behavior that are later used to validate and tune the target installation. In order to create meaningful benchmarks of the source installation, decide now how you plan to validate the target installation.
