I currently have a failed drive in my Array, that is currently covered by my single parity, while I wait for the waranty replacement to finally arrive.

The issue is: All my current drives, including parity, are 6TB drives. WD is sending me a 10TB drive as replacement, because they currently don't have any 6TB drives.

I'm not sure, what will be the right steps to correctly rebuilt the drive now, in this situation, since it's basically a Parity Swap, while still having to rebuilt something from Parity.

I know, that I can't add a drive bigger than the parity in the array. So the 10TB drive will have to be the new Parity.

Is there a special mode in Unraid, so that it knows, that it has to move the parity? Would it be better to add the 10TB as 2nd Parity, let it rebuilt, and then make the first parity the data drive? Evacuate the data with unbalanced? Kiss the files goodbye?

You can use the parity swap procedure.

Your scenario is exactly what the parity swap procedure is designed for. If you were just upgrading a parity drive without a failed data drive you just do a simple replacement.

Dang I should have read the guide to the end. 😅

Got too nervous on step 10 and stopped understanding what I've read around step 12 when 13 was the step that explained what I was confused about.

Thanks a lot!
