Migrating your data

You use the ndmpcopy command from the Data ONTAP prompt to migrate your data to the target volume.

Steps

1. Ensure that NDMP is configured correctly by entering the following commands:options ndmpd.enable on options ndmpd.authtype challenge
   Note: If you are migrating your volume between storage systems, make sure that these options are set correctly on both systems.

2. Disable data access to the source volume.
3. Migrate the data by entering the following command at the storage system prompt:ndmpcopy src_vol_name dest_vol_name

   Example

   ndmpcopy /vol/vol0trad /vol/vol0

   Attention: Make sure that you use the storage system command-line interface to run the ndmpcopy command. If you run this command from a client, your data will not migrate successfully.

   For more information about the ndmpcopy command, see the Data Protection Tape Backup and Recovery Guide.

4. Verify that the ndmpcopy operation completed successfully by validating the copied data.
