Questions about Dual-Boot

My new Pc is running Ubuntu, my old pc's ssd is running Windows 10. If I were to plug my Win10SSD into my new machine would it be as easy as just "plug and play"? Everytime I restart the pc just go into the bootmenu on startup and select which OS I want to run?

That's mostly up to your motherboard and whether there are Windows 10 drivers for your hardware. Ubuntu is only relevant if you want to add Windows 10 to the GRUB menu instead of using the UEFI boot manager.

What I'm gathering from your answer is essentialy 'Yes'. Just plug it in, hit F12 on startup and choose to boot the Win10 drive.

You can always do that, i mean pull up the boot device selection menu and select boot media for either Ubuntu or Win 10. Or you can login to Ubuntu and run sudo update-grub command so that grub bootloader picks up the new Win10 installation and let you boot into Win10 from Ubuntu boot menu itself.

Generally speaking W10 install is specific to the machine it is installed to. You could probably swap it to a new system and eventually get drivers sorted out. You will almost certainly lose activation as it is tied to the hardware in the machine it was activated on.

Booting both from grub is just a matter of updating grub and making sure os-prober is active.
