topic Migrating to 3140 in ONTAP Discussions https://community.netapp.com/t5/ONTAP-Discussions/Migrating-to-3140/m-p/75018#M17521 <HTML><HEAD></HEAD><BODY><P>Hello, first time posting on the forums.</P><P>I am migrating from a/a 3020 to a 3140. The 3020 is mirrored to fas270 at a dr site. The new 3140 head B has been setup with 2 DS14MK4 wi 300gb Fc drives. I going to move a sata shelf off the old filer and connect and assign it to the new filer head A. The sata shelf's flex vols are mirrored to the fas 270. Can i re establish the snapmirror without having to reintialize? Also what is the best way to migrate luns which are mapped via snapdrive,sme and smsql? TIA</P></BODY></HTML> Thu, 05 Jun 2025 07:22:02 GMT rajchoksey 2025-06-05T07:22:02Z Migrating to 3140 https://community.netapp.com/t5/ONTAP-Discussions/Migrating-to-3140/m-p/75018#M17521 <HTML><HEAD></HEAD><BODY><P>Hello, first time posting on the forums.</P><P>I am migrating from a/a 3020 to a 3140.

You'll want to make sure that the 270 is at the same or later ONTap version however (regular volume SnapMirror requirements).</P><P></P><P>For SME/SMSQL, you'll want to do something like....</P><P></P><UL><LI>stop SQL/Exchange/etc.</LI><LI>disconnect the LUNs in SnapDrive and remove them from the system</LI><LI>migrate the shelf to the new NetApp</LI><LI>make the LUNs available to the SQL/Exchange server from the new NetApp (igroup setup, LUN from an existing file -- this part I'm not quite sure of -- can anyone correct me here?)</LI><LI>using SnapDrive, connect to an existing LUN on the SQL/Exchange server making sure to use the same drive letters</LI></UL><P></P><P>I would model some of this if you can.....you don't have to move the shelf but could do some of it with a new volume/LUN/SnapDrive and testing the steps.</P></BODY></HTML> Mon, 16 Nov 2009 02:58:59 GMT https://community.netapp.com/t5/ONTAP-Discussions/Migrating-to-3140/m-p/75023#M17524 amiller_1 2009-11-16T02:58:59Z
