I'm sure this has been done before, but my gogoling has not yet provded me with the answer.  Everyone seems to take their UnRAID usb to the new hardware.  I wish to keep the usb with the old hardware, and just move the disk array. 

 

I have an unRAID server with a 24x 4tb (96tb) disk shelf plus an addtioanl 6x various cache/system drives in the main server case etc.  The main array is getting full (about 10% free), so I am plannig on buying another ebay disk shelf with 24x 6tb (144tb) drives.  

I don't quite need 240tb in unRAID at the moment (yet), so I am planning to transfer the 96tb disk shelf to a tempory UnRAID server (new or trial UnRAID license) - keeping all its array/files intact.   

Then using my current hardware, add the new disk shelf (144tb) to my existing server (keeping all its current caches, dockers, vms etc), create a new array, and copy all the data back over from the temporary server, and then shut the temporary server down until I need the additional space. 

 

Both new and old disk shelves (Netapp DS4246) + HBA (LSI 9200-16e) will be the same.  Server mobo + cpu etc will be different (Intel 11th gen i5 vs 4th gen i3)

 

Is there an easy way to do this?

 

Or can I mount all 48 disks on the single UnRAID at once (I'd assume as second pool) , transfer the data, and then disconnect the old shelf, making the new shelf the main array?

 

For some context, I'd prefer not to move the usb over as I am quite happy with how everything else is working on this hardware - various dockers, game servers, 8+ tb worth of LAN/Steam cache on the cache drives/pool.  I can re do it, I'd just rather not. 

Additonally, I'd rather not be removing/replacing a single drive and rebuilding the array 24x times.  I can happily leave the server(s) alone for a week while they transfer the data back to the new live server if i can safely move the entire array to a new UnRAID instance. 

 

 

You can just create a new array and copy the data over SMB or locally, locally you'd need to mount each disk individually with UD, cannot have two arrays.

Thanks JorgeB, just to confirm...

 

If I setup the new UnRAID server (new license), and plug the existing disk shelf (with it's array/data intact) into that hardware, as long as I create the new array with the original parity (2) and data (22) drives in the same/correct assignmnents on the new UnRAID server as they were in the old UnRIAD server... it should just work? 

 

Or am I missing anything further?

Correct, assuming no RAID controllers involved before or after.

Excellent - thanks for your assistance - time to order a new shelf and await delivery.
