From either the source or the destination site, perform migrate, failover, test failover, and reverse on already replicated workloads in VMware Cloud Director Availability.
- For existing replications, as either a tenant or as a provider, you can perform migrate, failover, test failover, or reverse by following the procedures in this chapter.
Table 1. Operational differences Perform migrate Perform failover Perform test Perform reverse Power state of the source workload: Powers off the source workload after the sync completes successfully. Does not change the power state of the source workload. Powers off the source workload before the operation initiates. Synchronization: The workload is failed over and cannot be synchronized until reversed. Allows synchronizing the target workload. Replication direction: Replication direction remains from the source site to the destination site. Changes the replication direction: from original destination where the target workload is up-to-date towards the original source. Workload target site placement: After performing migrate, the target workload runs in the destination site. To return the workload back to running in the source site, perform reverse. After performing failover, the target workload runs in the destination site. When the source site is available again, to return the workload back to running in it, perform reverse. After the test completes, the workload runs in both sites. To delete the test workloads from the destination site, perform test cleanup. The source site workload remains available and running in the source site. After performing a successful failover or migrate to the destination site, when the source site is available again, perform reverse and recover the target workload back to the source site. Once reversed, the target workload runs in the source site. - Alternatively, for information about creating new replications, see Create a protection or Create a migration.
