Batch migrations
Batch migrations are run as batch jobs from reusable batch migration plan files. Migration plan files are created using the
create-plan command.
A single batch migration plan can be for devices.
NOTE:Migrations consume cache resources. Running multiple migrations concurrently may impact host I/O.
Use batch migrations to:
- Retire storage arrays (off-lease arrays) and bring new ones online.
- Migrate devices to a different class of storage array.
The steps to perform a batch migration are generally the same as those described in the
General procedure to perform data migration.
There are two additional steps to prepare for a batch migration:
- Create a batch migration plan file (using the
batch-migrate create-plan command)
- Test the batch migration plan file (using the
batch-migrate check-plan command)
