Nodes (Area or Iteration) found in the history of the Source that are missing from the Target

[code-on-git]

I get an error message that I don't really understand:
There are 15 Nodes (Area or Iteration) found in the history of the Source that are missing from the Target! These MUST be added or mapped before we can continue

Followed by a list of areas and iterations that are missing like this:
MISSING Area: sourcePath=SourceProjectName\Area1, targetPath=TargetProjectName\Area1, anchored=True, IDs=n/a
MISSING Iteration: sourcePath=SourceProjectName\Phase2, targetPath=TargetProjectName\Phase2, anchored=True, IDs=n/a

I tried to solve this by adding the following config:
"AreaMaps": { "SourceProjectName\\\\Area1": "TargetProjectName\\Area1" },
"IterationMaps": { "SourceProjectName\\\\Phase2": "TargetProjectName\\Phase2" }

But I get the same error.

What does the error mean? Why can't the nodes just be created? I'm migrating to an empty project.

Area1 does not exist in the target.

If you want it to create the areas and iterations automatically then use: ShouldCreateMissingRevisionPaths

[MrHinsh]

ShouldCreateMissingRevisionPaths should create all of the nodes.

Ok, any possible reasons for why it could fail?

[MrHinsh]

Not that I am aware of.

[MrHinsh]

If the target area path is the same with just a change of project name then no mappings are required

This one seems to work in version 14.4.6.
