unfortunately test-a-TestNetworkMigration-test_01_native_to_native_network_migration-###### is still created and destroyed but a vlan is still allocated to it.

The problem seems to be not in the test but in vlan allocation leakage in the system. This can be merged but the left over from the test will remain, the scenario is valid.

As this is purely (test)cleanup, I don’t think this needs further testing , agree @vishesh92 @sudo87 @Pearl1594 ?

Yes. Just need to wait for test results to ensure that teardown gets executed successfully.
