New Unraid user & Migration questions

[SilasPMS]

Hello there! New Unraid user here, migrating from a QNAP NAS TS-871 to a Poweredge R510 12 bays just aquired.

 

I got a migration question: I want to move all my disks to the Poweredge. Currently, all the 6 To HDDs are located in my QNAP (Raid 6, I can lose 2 drives). Got 4 x 4 To drives (1 acting as Parity) + 4 x 1 To that are located in my poweredge (totalling 16 To). I got an external USB drive (8 To) that I am willing to shunk for Parity.

 

Got 30 To of data to migrate.

 

What would be the ideal solution?

 

I was thinking of this scenario: transfer as much data that is possible to the Poweredge, then shunk the 8 To, add it as parity drive, move the 4 To as disk for the array. Then remove two 6 To from the QNAP, add them to the poweredge and to the array, bringing the overall size to 32 To. Migrate the rest of the data, and install the remaining 6 To as replacement for the 1 To.

 

There is the small percentage of chance that a drive in the QNAP fails during the migration, which would be a bummer.

 

What would you fine people recommend?

Since drive redundancy is not a backup, and moving drives and data from system to system is one of the riskiest things you can do, I recommend obtaining as many new drives as necessary to keep a complete copy of your data intact somewhere.

I've been trying to do that but I am on a budget... Living in Switzerland, HDD prices are high and I can't get my hands on large drives right now. But thanks for the input, I'll try to find a temporary backup solution to store the data while I move the disks
