First step in the migration journey starts with understanding the customer’s Oracle setup, identifying the right size of Azure VMs with optimized licensing & deployment of Oracle on Azure VMs. During migration of Oracle workloads to the Azure IaaS, the key thing is to know how well one can prepare their VM based architecture to deploy onto Azure following a clearly defined sequential process. Getting your complex Oracle setup onto Azure requires detailed understanding of each migration step and Azure Infrastructure as a Service offering. This article describes each of the nine migration steps.

However, it's still up to the user to decide on which Azure VM type to select among the [many that Azure offers](https://azure.microsoft.com/pricing/details/virtual-machines/series/) keeping future requirements also in consideration.
