Here I have 4 Thread Groups present in my Test Plan and I have a requirement, need to run test plan in the time interval of 30 minutes between each of my Thread Group (2nd thread group should start only after 30 minutes, after the completion of 1st thread group and so on).

But cannot estimate the actual duration for all my thread groups. And my Ramp-up period should be 0 for all my thread groups, is there any solution to full fill my requirement ?

Thanks in advance
