Apologies for the delay and thanks for your patience.
There are multiple ways as mentioned in the article to migrate oracle to Azure VMs.
- Cross-cloud connectivity: If you already use Oracle Cloud Infrastructure (OCI), the easy migration path for you is direct interconnection between Azure and OCI. Go to Oracle database migration: Cross-cloud Connectivity.
- Lift and shift on Azure VMs: You can deploy your Oracle databases in Azure based on a "bring your own license" model. Go to Oracle database migration: Lift and Shift.
- Refactor: You have legacy Oracle code and you prefer using an Azure Managed Service. Go to Oracle database migration: Refactor.
- Rearchitect: If you're planning to retire your old code and redesign your architecture, Azure SQL Database Managed Instance is a good option. Go to Oracle database migration: Rearchitect
In your case Lift and shift on azure VMs seems better fit as it is related to existing license.
