Process template customizations differences between Azure DevOps Services and TFS

  • Стаття

Azure DevOps Services

Important

Import process supports the Hosted XML process model which allows you to manage customizations through updating select XML definition files of a process template. This feature is only available for organizations that have been migrated to Azure DevOps Services using the TFS Data Import Service.

If you use the Inheritance process model, you can customize your work tracking through the user interface by creating an Inheritance process. If you use the On-premises XML process model, you can customize a process template, see Upload or download a process template and Customize a process template.

To learn more about process models, see Customize work tracking.

Azure DevOps Services uses a different model than Team Foundation Server (TFS) for relating projects and process.

  • In TFS, process templates are used as starting points for projects and once a project is created, the project is the scope you customize.
  • In Azure DevOps Services, process is shared across multiple projects and is the scope you customize.

The structure and overall syntax used in defining process templates remains the same, with only a few minor differences existing between templates you customize for import into Azure DevOps Services and those you upload to support an on-premises TFS.

Note

Migration of projects or collections from Hosted XML to the inherited model is not support for Azure DevOps Server. It is only available on the Azure DevOps Sevice.

Unsupported customizations and unreferenced plug-in files

Any reference to the following objects in any of the XML definition files result in a validation error upon import.

  • Custom controls on work item forms
  • Custom link types
  • Global workflow
  • Team field support
  • For and Not rules support
  • Match rule support

The following plug-ins and their associated files aren't used in defining a process, nor used to update existing projects. However, they are used to create objects or artifacts when you create a new project.

  • Classification
  • Work item queries (defined using the WIQL syntax)
  • Test Management
  • Work items

Note

The WIQL length must not exceed 32K characters. The system won't allow you to create or run queries that exceed that length.

The following plug-ins and their associated files are replaced by system defaults.

  • Build
  • Groups and Permissions
  • Lab
  • Version Control

The following plug-ins and their associated files are ignored.
