Reordering Data Drives in Snapraid config? (alien.top)

I've read that changing the name of data disks in Snapraid is tolerated. However to my understanding changing the order of data drives in the Snapraid config will cause issues with parity.

For example when replacing two smaller disks for one larger 18TB HDD, I run into the issue:

Data Disks:

d1-Exos10tb (this drive to be replaced with larger HDD)

d2-Exos-8tb (drive also to be replaced with same large HDD from above)

d3-Exos20tb

d4-Exos16tb

d5-Exos14tb

I wish to replace d1 and d2 with one large HDD. How would I go about this operation?

If I just assign the new larger data disk as d1, what would happen to d2 and the the drives listed after it? Should I comment out the d2 line until I utilize that position with another drive, preserving the following disk's order? Or is there a better way to go about this?

To clarify if replace d1 with the new larger disk as d1 what will I do with the following drive order? Especially d2. Because by adding d1 as the new larger drive am I going to throw the following drives out of order causing a mandatory recalculation on my checksums. Or is d2 to be commented out or skipped entirely in my config. A step by step might help me more.

P.s. I have referenced the manual and FAQ and it doesn't go into specifics regarding drive order in the config.

Thanks
