I've got an unraid server that's sat unused since 2020. I want to move the install to all new hardware, and set it up from scratch. All my apps, plug-ins, dockers, etc are so outdated I'd rather just set it up again from scratch. Data on the array is replaceable so not worried about that either. Should I download a fresh copy onto a new stick, or delete configuration data from the old stick and try to update that? If I do update the old stick to (I think it's v7 now?), should that happen before or after moving it to the new hardware? Also is xfs still best for array disks? If there are any other considerations I haven't thought of please let me know, I don't want to overlook anything. 

 

Thanks

 

I'd start it up to verify that there really is nothing you want to keep. If there isn't, copy the key-file to a new location, and put a fresh copy of unraid on the USb and put the key-file back, then you can move everything to a new system or boot it up on the old if you want.

Thanks for the reply! I had already booted it, but hadn't looked thoroughly through the data. Turns out there are a few things to keep. The only other place with enough space to hold it would be the new server, but I only have the 1 license. Any thoughts on a possible route I could take? 

 

Thanks

Since the data is the most important thing, so keeping that safe is the best thing to do. So, I'd turn off autostart for the array and any VMs and dockers that may still be on your old USB, then move the USB and drives over to the new system, start it up, and see if it runs. If everything seems okay, start the array. To verify everything is okay, I'd run a non-correcting parity check next (e.g. disable 'write corrections to parity' and start the check).

 

Assuming everything goes okay, your data is now safe on the new system. Next i'd make a backup of the USB (click on Flash then flash backup). Also, make a screenshot of the drive assignments, and copy the keyfile from the USB, and I'd copy all that to the array as backup.

 

Next, shut down the system, and use the USB creator to erase the USB and put a fresh copy of the latest unraid on there, and put the keyfile back. Start the system with the USB, to make sure it works.

 

Now it depends on what you want to do, assuming you have new drives and don't want the old drives in the array, there's two ways to go about it. The first is to make a new array with the new drives, and then use the unassigned devices plugin to connect to the old drives and copy (not move) the data. This would leave the old drives and parity protected, so if something happens with the new drives, you can put the old array back.

 

The other way, is to assign one of the new drives as parity, and the rest of the old data drives as data, and let it rebuild parity. and then replace an old drive or add a new drive as data, and then move over the data to the new drive, then once all the data is on the new drive(s), make a screenshot of the drives, do a new config, assign parity and the new drives and remove the old ones.
