Migration og Project fails due to "FAILED to save..."

[frederic-siepmann-bl]

HI there!
I have a problem that I do not understand. I need to give you a little context and I hope you can help:
I want to merge a number of different projects within the same collection into one new Project called "Company Backlog". This new project already contains a few migrated projects (successfully done with this tool). I do have a "Test Migration Project" that shares the exact same process as the real project where I have successfully tested the config.

However, when I want to migrate the items (~3600) into the real project I do get the following error:

Sorry it is in German, but it is similar to the error mentioned here.

What I do not understand is why the error does not occur in the test project?
And am I right to assume that the System.IterationPath with "Value": "RnD Migration Test\Archive\STNA\3w\Sprint 2430", is the problem?

I do have a Sprint in the new project with the same name but with a different Iteration path. Is that a problem?

Any help is much appreciated. ;-)

We can only provide help with the latest version of the tooling. Please update!

Yes, they must be identical or mapped! We added the ability to map in v15.0.0/.
