= About the virtual machine storage migration process
|
|
|
|
During the migration, a `MigMigration` resource is created indicating what type of migration is happening.
|
|
|
|
The types of migration are as follows:
|
|
|
|
* Stage: Stage migration copies data from the source cluster to the target cluster without stopping the application. You can run a stage migration multiple times to reduce the duration of the cutover migration.
|
|
* Rollback: Rolls back a completed migration.
|
|
* Cutover: Cutover migration stops the transactions on the source cluster and moves the resources to the target cluster.
|
|
|
|
The status of the `MigMigration` resource contains progress information about any live storage migrations.
|
|
|
|
Any offline migrations contain the `DirectVolumeMigrationProgress` status that shows the progress of the offline migration.
|
|
|
|
Each `MigMigration` creates a `DirectVolumeMigration` if the migration plan is a direct volume migration plan.
|
|
|
|
To perform a storage live migration, a direct volume migration is required.
