Hello,
You can achieve this in different ways. After making sure the new key, you can do it mathematically and transpose the melody note by note counting the same distance in each note. While this would take some time, you could do it faster by writing it down if you are able to write/read music. Or if you learn your scales and accidentals for every key, then you could transpose it faster, easier and more accurately. Some basic Music Theory knowledge is necessary to successfully do this task. I hope this helps.
Best Regards,
Angel
