we are planning to migrate the data from Netapp to HNAS ..can any one suggest us what are the possible ways we can migrate ....?
We did that about five years ago and it was fairly straight forward. At that time there werent any specific tools to connect the two different storage arrays so we used robocopy and securecopy. Really liked securecopy as it would allow you to schedule copy jobs to keep everything in sync.
Once data was copied and permissions checked, shares were cut over. For nfs data we used our solaris boxes so permissions were retained.
Let me know if you have any questions.
Cooper thanks for your reply, we do have cifs shares which we are going to migrate so can you kindly suggest me the steps to follow
Once your volumes and shares are configured, copy/move data, apply permissions if necessary, serve data to users.
All depends on your environment.
Are you planning to use any HNAS storage features (ex. data migration, deduplication, multi-tier fs)?
Robocopy works fine, can be scheduled, and you can easily add the /MIR flag to do a full sync, but make sure you have your target/destination right. You also have the /MT option (multi-threaded) if that will help in your environment.
One suggestion, if you want to verify the permissions on the root folder for the shares are the same as the source before you copy, browse to the HNAS through the C$ share and drill down from there. I also use the path through the C$ share for the target in the Robocopy scripts. That way I know NAS admins will have rights to edit permissions through the share.
If you are tight on space and planning to use dedupe, you might want to copy half the files, enable dedupe and let it finish, then copy more. Similar for 'Data Migration' jobs.
Thanks Andrew and cooper, yes we are planning to use Robocopy only.....thanks for your valuable time
