Transfer to Munich

We travel to Dusseldorf next April, we have booked tickets from flight LH791 from Singapore to Dusseldorf, which takes us through Munich. The flight has just been updated: is Munich arriving now at 05:50 am and the flight to Dusseldorf is LH2002 at 06:30 am to Dusseldorf? Do we have time to transfer the agent to suggest well?
