OK, that's what I understood from what I read on business center and other help support.
The concrete use case is that I have an org structure which is completely blocked, I cannot make it evolve anymore without having coherence errors appearing. I had numerous exchanges with SAP experts in India and they concluded that the only way to solve the problem was to build a brand new org structure whether in the same tenant, whether in a brand new tenant.
The problem is that my customer does not want to loose its history for almost 2 years now. So we explore the idea of getting back all data from current tenant and upload them in a new tenant.
This is the reason of my question
