Check this answer music.stackexchange.com/questions/1467/…, your question is just a specific case. – José David Aug 29 '17 at 23:15
If you haven't change your tuning or your string height (from the fretboard), then no, you would not. Your new string may are fatter and with different gauge, but they are design to have same string tension. However, if you prefer different string height due to different string gauge you will definitely need a new setup for your guitar.
