Theres no K8. lol
There is no K6 either. They are all K5 or K4 with alterations or modification but, Hanbitsoft stopped production at K5. Anyhow as far as the databases you are talking about yes they essentially use the same databases with some small alterations as well. If you open your files and run them look at the logs. This is where you will discover any differences in the files that you are using and debug the databases to fix any problems you may or may not have.
