I have a laptop with three "drives" --- SDD1, SDD2, HDD1. Both SDD are 512 GB 2280 NVMe parts inside the laptop. I have a 1 TB NVMe part to upgrade one of the small devices. Can someone tell me how to accomplish the following?

/dev/nvme0 is home for /boot/efi and / as nvme0n1p1 and nvme0n1p2.

QUESTION: How do I clone those two partitions onto the new larger device using an NVME enclosure?
I've done this in the past with HDD devices and enclosures. I have the new larger device and an enclosure that I'm able to read-write from the laptop.
I tried running clonezilla but I must not understand the prompts and menu options well enough to get the results that I expect.
Because this involves an internal NVMe device, I'm not willing or interested in moving the hardware until I have a new larger part that appears to be what I want to deploy.

QUESTION: Will things "just work" to boot iI I succeed in cloning the NVMe parts?
In ancient times, the bootstrap needs specific knowledge of the drives and partitions and flags. QUESTION: After I clone the contents, will I need to use gparted to tinker the partition settings before the new larger part will boot?

Thanks in advance,

Are you going to keep the internal SSD you are trying to clone to the larger device or are you going to replace it? If you are replacing it and it has an efi partition, that will need to be cloned/copied to the new drive also. If you are still using Mint, there should be an ubuntu directory on the efi partition with a grub.cfg file in it. You need to change the UUID and drive/partition in this grub.cfg file to point to the new cloned device filesystem partition with /boot/grub after creating an efi partition on the new device and copying the files to it. Use the blkid command to get the new drive partitions UUIDs and change them in /etc/fstab and grub.cfg files.

You might also try using the boot repair ppa, the 2nd option described at the site below (if still using Mint) and reinstalling Grub to the efi partition on the new device.

Yes, my typical protocol is to clone an existing drive's entire content onto the new, larger drive.
Then I swap the new larger hardware into the system under revision and move the old, small drive
into an external enclosure. Initially, the enclosure part(s) are "archive" so that I can grab any parts of the
previous contents that I might need after the hardware swap.

Thanks for the heads-up about the EFI parts and need to tinker UUID settings before I try to boot the new larger clone.

Stay tuned...same bat time ... same bat channel,
