GRUB and switching SATA port

I'm about to install a second M.2 SSD to my rig, however doing so will disable SATA ports 5/6, which happens to have another SSD with Windows on it, so I'd have to move that to another port.

Using GRUB I have a simple Arch/Windows dual boot setup, although I'm worried it might break the moment I switch ports.

I figured it might be safer to temporarily remove the Windows entry from GRUB, switch ports, and then remount/add Windows.

Do you have any further advice? Or am I fine without touching GRUB at all?

UPDATE: I've done exactly as I've said above, and it works as good as before. Although I wonder if what I did with GRUB was unnecessary, so I'd still like an answer for that :)

Re: GRUB and switching SATA port

It wasn't necessary. In it's default configuration GRUB and more relevantly the logics that generate a config with grub-mkconfig use UUIDs to identify the partitions your bootable loaders are on and UUIDs are per partition and unique and should not be affected by port changes.
