Migrate

The migrate phase is where the actual migration of the workload takes place. In this phase, we perform migration as planned, monitor the migration process, and keep a plan in place to rollback in case issues encountered during the migration.

MIG-REL-08: Have you tested high availability (HA), fault tolerance (FT), and disaster recovery (DR)?

Test to validate that your workload meets functional and non-functional requirements before and after migration cutover. It is important to validate and update existing reliability components, which may be different in the new cloud environment.

MIG-REL-BP-8.1 Before the cut-over, test HA and FT for the migrated workloads, and perform a DR dry-run after the migration

This BP applies to the following best practice areas: Failure management

Implementation guidance

Suggestion 8.1.1: Follow the best practices (BPs) in the reliability pillar to complete the failure management testing for the migrated workloads.

This includes using playbooks to investigate failures, performing post-incident analysis, testing functional requirements for the migrated applications, testing scaling and performance, and testing resilience using chaos engineering.
