Best way to migrate luns from one NetApp array to another NetApp with minimal or no downtime

[Streethawk7789]

Hello,

I would like to move luns (presented to a windows 2008 server) from one NetApp FAS to another FAS. We have SQL databases runnign on it so would prefer online  migrations is possible. Can you suggest my options. 

I've used FLI to migrate from 3rd party to NetApp.

Thanks and appreciate your response.

Is this part of the new  same cDOT cluster?

Snapmirror is your friend.

Hi @Streethawk7789

Its better to go with snapmirror.

Like others have said, snapmirror if possible:

CDOT source?  snapmirror

7mode source with 64bit data (aggr,vols, AND snapshots)? 7MTT or snapmirror

7mode source with 32bit data (aggrs, vols, OR snapshots)? FLI, or upgrade to 64 bit and use 7MTT or snapmirror

Also review the SAN host remediation guide

Simply put
1.Create a SnapMirror relationship. cluster_source_vol-> cluster_dest_vol and initialize it to synchronize data2. Collect information about all luns lun show -v
3. When the change time arrives, stop the SQL service to prevent data writing
4. Perform the Snapmirror update for the last data synchronization
5.Quiesce, break SnapMirror
6. Mount the new lun on the target end to the SQL file
7. Start the SQL service
8. Check all mounted luns
