Requirement Based Test Suite not being migrated

I have this configurations,

        "defaultValue": "",
        "ApplyTo": ["Test Case"]
      }
	]
  }
}

TEST PLAN and SUITE Configuration:

 "Target": {
    "EndpointType": "TfsTeamProjectEndpoint",
    "Collection": "https://dev.azure.com/MyCollection/",
    "Project": "MyProject",

  }  
],
"CommonTools": {

    "FieldMaps": []
  }
}

}
}

Getting error for requirement based, target work item not found. and getting the bottom error about custom.reflectedworkitemid not existing. all my workitems were customized to even include both integration build and reflectedworkitem fields (test case, plans and suites),
The Requirement Based (234199) suite isnt being migrated while the static though migrated, contains empty test case.

What am i missing?

Have you validated that the work item that's referenced in the source exists in the target?

[DexLusterio]

hi MrHinsh.. yes. infact i have migrated the test cases first using the Test Case configuration above. Only the static suite contained the test case, while the requirement based was unable.

[DexLusterio]

already figured out the mystery. As it turns out, if a test case has link in other work item (ex. pbi), I have to run the configuration for that work item first and migrate that workitem, then subsequently run the test case, then the test plans/suites. I was trying to initially just migrate the test cases and test plan/rqmt based suites without thinking of the link between test case and pbi.
