Relocate files from extended drive to a new drive

I need to move an existing extended drive to a new drive on the same server. I found the procedure for using export/import metadata method, but that would double the amount of down-time for the server since all the data is copied twice.

What I'm hoping to do is disable the DX service and drivers (which I've done before in other troubleshooting), then use Robocopy to move all data on the extended drive to the new drive. At that point, I should be able to run the Sysinternals VolumeID utility to change the volume ID's of the two drives so that DX thinks nothing has happened after I re-enable the service/drivers. This part is actually part of the procedure. The only thing different is replacing the lengthy export/import metadata procedure with a single Robocopy.

Anyone have any thoughts on this?

Thanks!

Whether Robocopy will be able to copy a stub is a question. You could try it before you proceed.

Also, I have restored my metadata to a new volume in the past and it was quite fast. It's not the real data right? Just the pointers?

I would think that it would, but I'll test first.

The default meta-data export copies everything on the extended drive, stubs, unmanaged files, etc. So it's a lot of data. I'm thinking it'll take 3-5 hours to copy it once, so I don't want to have to do it twice.

Does anyone have any additional insite on this process? I need to peform the same procedure in my environment. I have gotten the length procedure to perform the migration from the EMC Support team but would like to know if there is a faster way to peform the migration rather than exporting all meta data first.

Could it be as simple as disabling services and drivers, use Robocopy to copy data from one drive to another, rename old drive letter and volume id, reboot, rename new drive letter to old drive and change volume id to match old drive, reboot, restart all services and re-enable all drivers.

Any help is also greatly appreciated.

Thanks

I did exactly this as we had corruption on our original extended drive and had to migrate the content to a new extended drive.
