Add partitions

SQL 2012

I have an existing partition function which has about 50 partitions (by date).  As the “last date” approaches, I want to modify the function and add 50 more date partitions so that as new data comes into the table, it gets put into the new partitions, rather than on the last partition (which is what would happen if I don’t extend the function).

All this being said, do I also need to modify the partition scheme?  Or only the function?

Thanks, Andre
