We acquired a company and are trying to migrate their separate Jira cloud instance to our Jira cloud instance.
I have validated permissions. I am an Org & Site Admin in both instances. When I try to perform the migration, the destination site dropdown isn't selectable.
I found this thread and am not following what it was that made it work for this individual. I went into the source site and created a new user with a different email domain, granted them Org admin rights, and the same thing is still happening.

Would someone be able to offer guidance on what else I need in place? I've already nested the source site Jira instance under our destination Jira, so I can toggle between the two, I just can't migrate it for some reason.
