How to get json object property without using OPENJSON

Question

Following is my script to get specific value(OldPTValue, NewPTValue) from table HistoryTracking .
I'm using OPENJSON but getting compatibility issue.
Is there any way to get data without using OPENJSON in sql server 2016?

SELECT 
    (
        SELECT [Number] 
        FROM OPENJSON( CHT.OldValues, '$.Employee' ) 
        WITH ([Number] NVARCHAR(25) '$.PaymentTerms')) AS OldPTValue, 
    (
        SELECT [Number] 
        FROM OPENJSON( CHT.NewValues, '$.Employee' ) 
        WITH ([Number] NVARCHAR(25) '$.PaymentTerms')
    ) AS NewPTValue,
    CHT.InsertedBy,
    CHT.InsertedDate 
FROM HistoryTracking CHT 
ORDER BY CHT.Employee, CHT.InsertedDate desc

I may be wrong, but it seems like that's what you may need there. https://docs.microsoft.com/en-us/sql/relational-databases/json/json-data-sql-server?view=sql-server-ver15
