Open Migrator questions
For a fear being shunned and labeled as anti-EMC ( ), I am wondering if Open Migrator can be used to migrate data from a Clariion to a non-EMC storage platform? The product brief makes mention of "any source to EMC storage", but the install/config/admin docs do not describe that limitation. So is there a definitive answer?
And secondly, I've been trying to figure out there's any cost associated with the OM use and can't come up with a definitive reference. Does anyone have a recent experience with its use that can chime in?
Thanks in advance.

The connection can be to any SCSI attached storage platform, but the limitation of Open Migrator is that it will only migrate data to EMC storage. It will not allow you to migrate to a third party storage array.

Open Migrator Product Guide says
The connection can be to any storage platform and can be direct,
through the Enterprise Storage Network, or on the SAN,
operating over SCSI or Fibre Channel.
I do not see anywhere it is denied that it cannot be used to migrate volume from third party arrays. Also note that since Open Migrator is a Volume based migration, it attaches its filter driver to the volume that needs to be migrated. Since a volume can be on any of the SAN disk, it is not necessary that it must only be EMC Storage.
Also note that Open Migrator is a free software available from EMC and no license is required. Once the migrations are done following the procedure in the Open Migrator Product Guide, uninstall Open Migrator from the host.

In the past the migration from Netapp volume to EMC storage based volume worked in a case. I believe what you have mentioned also points to the same:-
EMC® developed the EMC Data Migration Solution for Open Migrator/LM service to provide online data
migration of Microsoft Windows, UNIX, or Linux volumes between any source and EMC storage.

One example of this is documented in the EMC Fact Sheet
EMC Corporation Technology Solutions Kit: Fact Sheet

Yes Dynamox
You are correct. There is still no support for system drives C:.

does that buy me anything, at this point it's an offline migration and i could accomplish the same thing using some other 3rd party cloning tools ?

There is the possibility it will be faster with OM, but I can't imagine the system disk is so large it will make a difference.

Yes, any source, but the target must always be EMC.

Thanks for the replies all. I was afraid the target is EMC devices only, but oh well. Back to the drawing board.

Dynamox, you are correct. Unless of course you mark it inactive and mount to another server for the migration.

Hi Maliboo, you stated that OM is only supported as an any-source to only EMC storage systems as target. Does that include EMC Isilon as a target?
IHAC who is migrating their data off of EMC VMAX & CLARiiON onto an Isilon array that will be configured with NFS file systems for file-level data and iSCSI devices for block-level data. We would likely use rsync, MS RichCopy, or SecureCopy to migrate the file-level data but are uncertain what to use for the block-level data migration. OpenMigrator LM was suggested but Isilon is not yet listed on our E-Lab Interoperability Navigator portal.

Hello,
Documentation states Symmetrix and Clariion as supported target arrays. I don't see any reference to Isilon as a supported target array. Unfortunately, I don't have access to an Isilon to test.
Sorry.

i do have access to Isilon but i do not have access to OM, is it still a license product ?
