Do I record each partnership on separate K-1 forms and are they exclusive of each other?

I received two separate K-1s as the partnership was acquired by another partnership in October 2018. The number of unit shares form first partnership were converted to more unit shares with new partnership.

Yes, you report them separately.  This is similar to receiving W2s from a company that changed ownership:  you have to report them both separately because the income adds together, and the documents themselves are issued under two different EINs, so they have to be accounted for on your return separately.
