Encountering the “VS402831: Cannot move or copy work item” error in Azure DevOps can be a frustrating roadblock, especially when you’re trying to streamline your workflow by migrating work items between projects. This common issue arises when attempting to move a work item from one project to another project within the same Azure DevOps organization.
Why Can’t You Move or Copy Your Azure DevOps Work Item (VS402831)?
The VS402831 error typically signals a mismatch or conflict between the source and destination projects. Here are the most common culprits:
- Mismatched Process Templates: Perhaps the most frequent cause, this error often occurs when your source and destination projects are built on different process templates (e.g., Agile, Scrum, CMMI, or a custom process). Each process template defines specific work item types, states, fields, and workflows. If a work item from a “Scrum” project, with its unique states like “Committed” or “Done,” is moved to an “Agile” project that might not have those exact states or field definitions, Azure DevOps throws an error.
- Invalid Field Values in the Destination Project: Work items contain various fields (e.g., State, Reason, Area Path, Iteration Path, Custom Fields). If a value for a specific field in your source work item isn’t recognized or valid in the destination project’s configuration, the move operation will fail.
- Example: Imagine you’re moving a “Bug” from Project A where it’s in the “Active” state. If Project B (the destination) does not have an “Active” state defined for its “Bug” work item type, or if the “Active” state has different rules or transitions, you’ll encounter the VS402831 error. The system simply doesn’t know where to place that work item’s current state in the new project’s workflow.

If Project B (the destination) does not have an “Active” state defined for its “Bug” work item type, or if the “Active” state has different rules or transitions, you’ll encounter the VS402831 error. The system simply doesn’t know where to place that work item’s current state in the new project’s workflow.
- Conflicting Rules on the Destination Project: Azure DevOps allows you to define custom rules for work item types and fields. These rules can dictate field visibility, required fields, transitions, and more. If a rule in the destination project conflicts with the state or values of the incoming work item, it will prevent the move. For instance, a rule might make a certain field mandatory upon moving to a new state, and if that field isn’t populated or isn’t valid, the move fails.
How to Resolve the VS402831 Error: Corrective Steps
Identifying the root cause is the first step; taking corrective action is the next. Here are the primary strategies to overcome the “Cannot move or copy work item” error:
- Temporarily Disable Rules on the Destination Project (Use with Caution): For quick troubleshooting, you might consider temporarily disabling specific rules on the destination project that could be blocking the work item move. This is often a last resort and requires a good understanding of the potential impact. You would navigate to Project settings > Boards > Process > (Your Process) > Work Item Types > (Specific Work Item Type) > Rules and temporarily disable the problematic rules. Remember to re-enable them after the move if necessary.
- Add Required Values/States to Fields in the Destination Project: This is often the most straightforward and recommended solution. Before attempting the move, ensure that any “missing” states or field values from your source work item are explicitly added and configured in the destination project’s process template.
- For State Mismatches: Go to Project settings > Boards > Process > (Your Process) > Work Item Types > (Specific Work Item Type) > States. Add any states that exist in your source work item but are missing in the destination. You might also need to adjust transitions.
- For Field Value Mismatches: For picklist fields, ensure all necessary values are present. For custom fields, ensure their definitions align.
- Change the Process Template of the Destination Project: If you’re facing persistent issues due to fundamental differences in process models, a more comprehensive solution might be to change the process template of the destination project to match the source project’s template. This is a significant change and should be carefully planned and executed, as it impacts all work items and workflows within the destination project.
- To do this, navigate to Organization settings > Process. Select the process of your destination project, and then choose “Change process” to align it with the source project’s process. Be aware that this can cause data loss if fields or states exist in the old process but not the new one.
Best Practices to Avoid Future VS402831 Errors
- Standardize Processes: Whenever possible, aim to use a consistent process template across projects within the same organization, especially if you anticipate frequent work item transfers.
- Plan Migrations: For large-scale migrations, consider a pilot phase to identify and resolve any process or field mismatches before a full-scale move.
- Utilize Azure DevOps APIs/Tools: For complex migrations or bulk operations, consider using Azure DevOps APIs or third-party migration tools that offer more granular control and error handling.
By applying these corrective steps, you can efficiently resolve the “VS402831: Cannot move or copy work item” error and maintain a fluid work item management process in your Azure DevOps environment. If the issue persists, always double-check your process template configurations and field definitions in both the source and destination projects.
