Version 8.9.2 - when I run an Azure DevOps to Azure DevOps migration using base Scrum process (modified with inherited process that adds ReflectedWorkItemId to WITs), I observe save exceptions for a small percentage of the work-items during migration. After migration, I find empty work-items created with no title. Example:

I have reproduced this error using the following steps: 1. Setup modified/inherited Scrum process "Migration" with "ReflectedWorkItemId" added to appropriate WITs on two separate Azure DevOps organizations 2. Setup source and target Projects "Migration test 2" using the Migration process configured in (1) 3. Create and save Product Backlog Item WIT in source project with Title "Test Changing PBI to Task" 4. Change type of WIT just created to type Task. Resolve State field issue by changing from "New" to "To Do" and save 5. Setup configuration.json configuration based on default ("init") generated json w/ typical modifications per video (empty field maps, etc.). Enable iteration processor and WIT processor. Modify QueryBit for WIT processor to exclude only Test Suite and Test Plan WITs. Set ReplayRevisions to true. 6. Run migration (on the one WIT created and modified in (2) and (3)). Error reproduced:

(SessionID: 6984b357-03ec-401d-ba03-7d43c84c4c6e)

Found 'Custom.ReflectedWorkItemId' in this project, proceeding.

After reviewing the documentation, I found the SkipToFinalRevisedWorkItemType configuration element for the VstsSyncMigrator.Engine.Configuration.Processing.WorkItemMigrationConfig processor. The docs are a bit cryptic, but I tried setting this configuration element to true and found it eliminated the save exceptions, resulting in successful migration and no blank-titled work-items.

I searched all issues and did not find mention of the SkipToFinalRevisedWorkItemType except in one closed issue that included a configuration.json listing.

If the intended functionality of the SkipToFinalRevisedWorkItemType is to address this Save exception, I would suggest a documentation update to indicate that work-item types that were changed will fail to save when replaying revisions unless SkipToFinalRevisedWorkItemType is set to true. Ideally, a code update that resulted in more graceful/informative exception handling would be added, if not functionality that could successfully navigate work-item type changes when replaying revisions.

If none of those options are possible at present, then this issue can be closed to serve as nominal documentation.
