Converting Column Names in Apache NIFI (Oracle)

[#1]

Good Morning, I have a problem with conversions in NiFi.

I have a large amount of tables in Oracle that I need to transfer via NiFi into one of ten set tables. I am very new to NiFi and am running into a big problem in which I have a column name in Nifi i.e "Birthday_Date" but the column name for that type of value is "B_Day_Date" in the new preset tables. How would I go about converting this in Nifi?
