I hope someone could help me.
I’m trying to convert a database to 2013 R2 using the new version of the Upgrade Toolkit (http://blogs.msdn.com/b/nav/archive/2013/11/22/upgrade-toolkit-for-upgrading-data-from-microsoft-dynamics-nav-2009-r2-and-microsoft-dynamics-nav-2009-sp1-to-microsoft-dynamics-nav-2013-r2.aspx)
In my database I have 3 Companies. I have managed to perform step 11 (transfer data) for 2 Companies, but in Company 3 I got this error: “A call to System.Data.SqlClient.SqlCommand.ExecuteReader faile with this message: There is already an open DataReader associated with this Command wich must be closed first.”
I have tried to restart the Nav Service and have also tried to restart the server, but the same error shows up when I try to perform “Transfer Data”.
