Moving partition from one disk to another

I have the rog strix x570-e gaming motherboard, which has 2 equal NVME M2.2 SSD slots.

Up till now, I had been using only a single M2.2 1TB SSD with a both Windows 10 and Ubuntu 20.04 installed. My 1 TB SSD was getting really full, so I purchased the same one again, and plugged it in my motherboard.

I would like to maintain a dual boot, but only have 1 OS on each SSD. Therefore, I would like to either:

A) Move my existing Windows partition to the new SSD, and keep the Ubuntu one as it is, or

B) Move my existing Ubuntu partition to the new SSD, and keep the Windows one as it is

I am unable to move partitions across drives easily so far, and I ideally don't want to have to reinstall a new OS altogether, rather simply moves my files onto the new disk's formatted filespace (NTSF or Ext/ExFAT depending on whether I chose option A or B).

Which option would be easier, and how can I do it ? I have the following partitions (removed all the snap loops):

eklavya@eklalinux:/$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
nvme0n1     259:0    0 931.5G  0 disk 
└─nvme0n1p1 259:1    0 931.5G  0 part /media/eklavya/UbuntuDisk
nvme1n1     259:2    0 931.5G  0 disk 
├─nvme1n1p1 259:3    0   100M  0 part /boot/efi
├─nvme1n1p2 259:4    0    16M  0 part 
├─nvme1n1p3 259:5    0 735.6G  0 part 
├─nvme1n1p4 259:6    0   505M  0 part 
├─nvme1n1p5 259:7    0 195.3G  0 part /
└─nvme1n1p6 259:8    0    33M  0 part

(For now I formatted the new disk into Ext4 Linux FileSystem, and called it UbuntuDisk)

Thanks

I know you do not want to reinstall, but that is the better choice. Install & use rsync to copy configuration & data. Best to install & restore from your normal backup, as you still have install to add any missing data to backup. I did test install of kinetic, with ISO booted from grub, partitions already defined, install on NVMe drive was less than 5 min. Longest time was downloading apps from backed up list of manually added apps. Rsync data was very fast. see this: https://askubuntu.com/questions/16988/how-do-i-install-ubuntu-to-a-usb-key-without-using-startup-disk-creator

Ok then. I guess I will just install Ubuntu on the new disk and move/reinstall the data stuff.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
