We have installed and upgraded the GP from lower version to the upper version of the GP. We have restored the SQL server on the new installed SQL server. Once we upgraded the GP2010 to GP 2016R2 without any error and while testing the workflow it was giving an error. To solve this error you need to run the one store procedure against DYNAMICS Database and this error will be solved.
