Change map layout on mobile version

Is there a way to change the map type please ? I saw that it is possible for pc version but for mobile-tablet version ? I want to change, I don’t like my riverland map and I’m in my 3rd year

Thank you by advance

 

You can't change the map type, even on PC, on an already existing farm.
New map type means new farm..

 

You can change farm layout by transferring your save files to PC, editing the save file, and changing the farm type (see one of the online guides like this one). I suggest clearing all the trees, debris, crops, etc off your farm first so you don't have stuff floating in lakes and such.

 

I did it and it worked very well ! Thank you and have a nice day !
