but my operation is export a lifecycle template from system1,then cancel this template,then import that template to system1.So I think the version is same.And I try to import this template to another system named system2,successful.It is too strange。system1 is dev,system2 is test
Confused, why are you exporting and then importing to the same system? You mentioned system1 twice. I can see it now allowing the same lifecycle to be imported back in. Did you try changing the filename of the import file?
