I need to move my entire mac os to new ssd and use it externally

As i said above .. my internal ssd causes heating issues and i am afraid that it'll destroy my nvme ssd

So purchased an 512 sata ssd

So i wish to move the entire mac os partition with same data from nvme ssd to my new 512 gb sata ssd

And also i need to boot it externally from external drive..

Anybody have any idea how to archive this? .

And also i am trying to move partition from within windows..
