The spinning disc drive is SATA and non proprietary (https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2546+Bla...). The SSD is not and use a proprietary PCI-e connector (https://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2546+Bla...). You can find adapters though (https://www.amazon.de/Sintech-M-2-PCIe-2280-SSD-Karte-MZ-JPU...).
I cloned to a USB drive, swapped the SSDs, and then booted up with the USB drive, and cloned back to the new SSD.

You will need an NVMe SSD adapter similar to this https://www.amazon.com/Sintech-Adapter-Upgrade-2013-2015-Mac...

You can also download old versions of MacOS installers. I forget the link to the easier scripts/installers, there's a High Sierra one at http://dosdude1.com/highsierra/
Personally I ended up using ./installinstallmacos.py from https://github.com/munki/macadmin-scripts to grab the catalog contents
and then temporarily blocked swcdn.apple.com in /etc/hosts,
and then served the /content/ directory so that swcdn.apple.com/content/ was pointed at 127.0.0.1/content (I used python here in the parent directory of /content/) > sudo python -m SimpleHTTPServer 80
and then I opened the High Sierra MacOS app store specific link to make it download & assemble the .dmg file properly
Open in Safari to ensure it launches App Store https://itunes.apple.com/us/app/macos-high-sierra/id12462847...
Can use the same approach to grab other versions of MacOS downloaders from apple too if you look up the app store links for it and then serve the catalog locally I guess.
