Yesterday, I blogged about the migration activities to get to TFS 2015 RC2, but I was still stuck at an error during new Team Project creation.
Looking into the logs it looked like there was some kind of issue during the upload of the first Reporting Services report “Bug Status” (part of the latest TFS 2015 Agile process template).
First I thought there was something wrong with permissions on the Reporting Services site because I also applied a certificate to offer accessibility via https, but that wasn’t it. All seemed to be setup correctly. A sign to look further into the details of the Bug Status .rdl report definition and why it couldn’t be correctly uploaded to the Reporting Services site. After downloading the process template from the Team Project Collection and opening the report with notepad, I knew I was getting closer to the root cause.
As shown in the picture above, the (default TFS 2015) Data Source mentioned in the report definition did not exist in the Report Server database after the migration from TFS 2010 SP1. In the TFS 2010 timeframe, all report defintions were linked to a “2010” Data Source.
Instead of renaming the existing Data Sources (that would break the existing reports, created from a TFS 2010 Team Project), I duplicated the entries to provide extra Data Sources with the expected names for usage with TFS 2015.
Issues resolved. Back on track!
