How-To: Creating area and iteration maps

[MrHinsh]

As per the documentation, you need to add Iteration Maps and Area Maps that adapt the old locations to new ones that are valid in the Target.

Before your migration starts it will validate that all of the Areas and Iterations from the Source work items revisions exist on the Target. Any that do not exist will be flagged in the logs and if you have "StopMigrationOnMissingAreaIterationNodes": true, set the migration will stop just after it outputs a list of the missing nodes.

Our algorithm that converts the Source nodes to Target nodes processes the mappings at that time. This means that any valid mapped nodes will never be caught by the This path is not anchored in the source project message as they are already altered to be valid.
