I have an Oracle Analytics Cloud instance in Oracle Cloud.
Is there a way to move it to Azure? I understand that OAC is PaaS, so I'd say it is not a way to move it as is. But I'd appreciate a confirmation of this assumption.
Also, just wondering if switching OAC to classic instance (doing the opposite of this article) and then upload that VM to Azure cloud, IaaS.
OAC only runs on Oracle Cloud. The "Classic" you mentions isn't available to buy anymore since a long time and only legacy customers are still running it.
If you want to run Oracle Analytics on Azure you'll need to go for Oracle Analytics Server.
