Archive Lightroom Classic Library to switch to Lightroom Cloud

If you don't want your 10 years of Photography in the Adobe Cloud, but do want to be able to "see my edits and change a thing here and there" why don't you simply sync your Lightroom Classic with the Lightroom cloud? That allows you to select all of your Classic images (or as many or as few as you prefer) and sync them to the cloud....but Classic only uploads Smart Previews, not full res originals, and which are 2560 pixels on the long edge and are generally more than good enough for viewing on your iDevices or the Web, and doing some editing as well. Any changes made on any of the synced devices will sync to all the other devices, so you'll always have the latest version of the image wherever you are....and best of all NONE of those Smart Previews count against that 20GB allowance.....so you can put all 10 years of youir Photography in the cloud as Smart Previews at zero additional cost.

Lightroom Cloud versions only works in the cloud in regards to your files. To access the files and their edits, they'd need to be in the cloud. That's just how it works. 

When a sub runs out on Classic, you can still access and export files. You can even still apply presets via Quick Develop, but no Develop or Map module work can be done.
