How To Restore App+App Data from a KitKat Nandroid Backup to Lollipop topic

I have searched so many times and I have no clue how to do this. I have tried just using nandroid manager to restore but it ends up just restoring the app, not the app data..
Is the only true solution to this would be restoring the kitkat nandroid and using titanium backup all my apps?
Thanks for the halps.
