It’s just something I was exploring today in preparation for the MB2-715, and, it seems, there are ways to move instances from one tenant to another without having to actually migrate the data. At least that seems to be the case according to the discussions here:
This is likely going to involve a support request, but, nonetheless, it should be doable..
I was told through one support request that the instance could be moved to another tenant with a support request but only because it was on v8.2.2. If the instance would have been upgraded to V9 then you would have to do a data migration.
Thanks, Heikki. Sounds like we should normally go with “not doable”, after all.
