So I've worked my way through all the migration hoops:
- anonymized users
- deleted projects, users and filters where possible
- upgraded Jira to a version that actually supports Cloud Migration (n.b. this excludes the latest 8.16.0 which doesn't support Cloud Migration).
Anyway, the migration is complete. I can see the projects in the project list. The migration said you might not see be able to access projects/tickets for some time but it's been a few hours now and I can't access any of the imported projects/tickets. What do I do now?
