Does not work for Test Plans test suite and Test case link

i want to migrate test plan , test suite and test case from one project to another .

it is migrating all test case , test plan and suite but the link between them is not getting migrated . if i go to test plan module and open my test plan it will not reflect my test suite and test cases.

is it possible?

i have attached the screen shot form source project , i want same in target project as well.

You can't migrate Test Plan or Test Suite items as there is no way to "wire" them back up to each other afterwards.

Using the Azure DevOps Migration Tools you will need to run the WorkItemMigration tool to migrate the Test Cases, and any other required items. Once you have all of the Test Cases migrated you can use the TestPlansAndSuitesMigration to create a new plan and suite structure that as closely matches the original as possible.

Note: You will need to migrate any other Work Items, I can see Requirement bases Suites in your screenshot, that are referenced as well.
