This topic describes methods to migrate data.
Data migration applications
Data migration has the following characteristics and applications:
- Storage partitions can be non-disruptively migrated between systems
in a FlashSystem grid. For details,
see Migrating storage partitions between systems.
- The system supports migrating existing volumes to a data reduction pool with volume
mirroring. For details, see Moving volumes to a data reduction pool.
- For systems with encryption enabled, you can migrate existing volumes from
non-encrypted pools to encrypted pools. For details, see Migrating volumes to an encrypted pool.
- Changes the MDisks to which the volume is allocated.
- Does not disrupt access to the volume data.
- Can be used when you are removing MDisks from a clustered system.
- Can move data to an MDisk that has appropriate performance for host requirements.
- Can move data from image mode volumes to MDisks when you are adding a system to an existing SAN
infrastructure.
- Can migrate striped and sequential volumes to an image mode volume.
For more information on the command-line interface, see Migration commands.
