I had a few packages created with Windows Authentication which now needs to be migrated to run with SQL Server Authentication. I tried changing it in the connection managers but the packages failed to validate at the SCD transformations.For a few packages I had Configuration files for these packages where i tried to do it but it dint run giving the following Error Message:
[Connection manager "Target"] Error: An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Login failed for user <<with my network id>>.".
[Execute SQL Task] Error: Failed to acquire connection "Target". Connection may not be configured correctly or you may not have the right permissions on this connection.
Target was the name of my connection.
