{{header_en|title=StudioSG - Migrating a shared file system to a Celerra NAS| keyword={{Template:Keyword_en_nas_san}}| description=How to migrate a network shared file system on a Celerra NAS by EMC using the CDMS service | link_page=celerra_data_migration_service}}

The CDMS service allows to migrate shared disks and file systems from heterogeneous sources to a Celerra Disk Array through the '''NFS''' or '''CIFS''' protocol. Using CDMS the data unavailability gap can be minimized while shares read or write access can be guaranteed throughout the whole migration process. Many file attributes: user permissions, last update date, last access date and such '''are preserved after the migration'''.

Prior to migrating the share, some checks need performing: mainly network infrastructure and data source checks.

Checks and pre-migration activities are over; we'll now copy data from the source to the target file system.

Once the data copy is over, file system type is to be changed from '''mgfs''' to standard Celerra format. Connect to the Celerra Control Station using the '''nasadmin''' user account and issue command:

This paper listed and described some of the many steps needed to perform a NFS shared file system migration. The shared disk was moved from a generic file server to an Emc² Celerra family Network Server. The CDMS service was used to perform data migration.
