SAP BW Dataflow Connector

Same issue here - we have multiple reports that query several dataflows that have several BW queries hooked up so having to rebuild and reconnect all of the underlying datasources in all of the reports would require A LOT of effort - is there a fix being worked on currently and what is the ETC, thanks.

[Edit 2 hrs later]:

I did some testing by trying the JSON export/import option suggested above - this one didn't work for me because I have a broken query (my data source has changed) which I cannot modify so the moment I go into dataflow edit mode I continue to receive the same "DataSource.MissingClientLibrary..." error. 

Also tried creating a blank dataflow and copied over some of the BW queries from the "problematic" dataflow - this workes only if you don't have to edit the dataflow once saved & closed... the moment you open up the dataflow for editions it throws back the same SAP.NET Connector library error and you are back to square one... 

Frankly, this is a major issue for our organization - really frustrating if I have to rebuild the whole dataflow model and all connections flowing from it in order to be able to bring back organizational reporting back to production, before MS releases a fix which looks like at this point is not even even acknowledged by MS as a problem... very disappointing...
