We have a customized version of the Agile template that we've been using since TFS 2013. I have upgraded the template for 2015, which was no big deal. But when I go to upload it I get error "VS402479: You can't overwrite the Agile process template, because it's locked".
I have followed the instructions from MSDN to upload an updated process template. I have changed the name, description, and minor version strings as described in the documentation.
Here are the values from the metadata node in my ProcessTemplate.xml file:
<name>Custom Agile</name>
<description>Custom Template based on MSF Agile</description>
<version type="ADCC42AB-9882-485E-A3ED-7678F01F66BC" major="14" minor="20" />
I have tried changing the major version and the minor versions to different, higher increments, and receive the same error.
If I change the type to a different Guid, the template loads just fine. The instructions imply that the Guid should be the same. I'm assuming this is so TFS knows the relationship between the built-in templates and custom templates they are based on.
I have a bunch of team projects to update the features on once the upgrade is complete and do not want to break the relationship to the built-in Agile process template if I can help it.
