Power Query from cloud based server and on premise server and union both table together by function

[Anonymous]

I am in Power Query and I am given a custom function: to query from TWO different SQL servers - before they are different SQL servers but both on premise and right now I need change one server to Cloud version. 

After change, I was thrown this error message:  DataSource.Error: Microsoft SQL: Could not find server 'AAASQL' in sys.servers. Verify that the correct server name was specified. If necessary, execute the stored procedure sp_addlinkedserver to add the server to sys.servers.
Details:
DataSourceKind=SQL
DataSourcePath=BBBSQL;CSA

You have to create a new data source to then connect to the azure db, instead of recycling the current connection.
