we upgraded a TFS2017 to Azure Devops Server 2019. We had a custom XML process template on TFS2017 that we want to migrate to inherited processes. But we cannot see this process template in the process page. We only see the inherited processes (Agile, CMMI, ...) and the basic XML templates which where migrated ("Microsoft Visual Studio Scrum 2013.3", "MSF for Agile Software Development 2013.2", ...) There is a project with this custom template and we can update the process with WIT commands.
Does anyone know how to make this custom process visible in the process page? then we will be able to migrate it.
