As a part of my clients CKEditor 5 upgrade we are running both CKEditor 4 and 5 simultaneously which is making our initial testing considerably easier.
Currently v2 only support CKE4 and v3 only supports CKE5. It would be so much better if we leave the support for CKE4 in v3, and then remove it in v4
