I don't see this exact question in the prompted similar questions, so if it has been asked in a different form before, please forgive me.

I currently have 20.04 on my HDD and plan to upgrade to 22.04 (installed to an NVMe SSD) when it is released. I would like to dual-boot for a little while so I can test and make sure the new setup works as I want it to, then I will switch over fully to the 22.04 on SSD and drop the dual-boot. Can anyone suggest the best way to handle this?

Thanks!

EDITED TO ADD: From some of the comments, I realize that I did not make clear enough that my question is not about the testing phase as much as it is about the migrating from HDD to SSD boot drives with a dual-boot phase in between.

I'm still looking to see if there is a clear answer to the question of where GRUB should live during the dual-boot phase: should I put GRUB on the SSD when I install 22.04 or wait to move it there when I remove the HDD?

grub can be installed on either of the two drives, and there's no point in moving grub to a different drive if it's not necessary to relocate it. During the dual boot phase you can leave grub where it is, and then reinstall grub after you remove the HDD.
