First, you have to review the previous question and the answers given on it. If those answers are still relevant to the OS you're interested in, then you should not post a question. If you are able to, add a comment to the other question or answers noting they still apply on the newer OS.
If the solutions on that previous question do NOT solve the problem you're having, you need to determine whether this is due to the OS difference, or some other issue. As you write out a new question, recognize the previous, and clearly note your efforts to solve your problem using the solutions proposed there, and how those failed to do so.
Frankly, this isn't specific to OS-difference issues, this is just the steps anyone should follow on this site any time they find a question that is similar to their own but for which the existing answers do not solve the problem. Use the information in those existing Q/A sets to guide your own troubleshooting and self-resolution efforts, and record all that as you write your own question. This helps on several levels: It results in a better question by clearly demonstrating self effort and recording research done, and it makes it more clear the previous solutions don't work to a duplicate flag is less likely to happen.
