### How do I build a business case?
3838

3939
Currently, you can create a Business case on servers and workloads discovered using a lightweight Azure Migrate appliance in your VMware environment. The appliance discovers on-premises servers and workloads. It then sends server metadata and performance data to Azure Migrate.

We couldn't collect sufficient data points to classify these servers. We recommend that you wait at least a day after starting discovery so that the Business case has enough utilization data points. Also, review the notifications/ resolve issues blades on Azure Migrate hub to identify any discovery related issues prior to Business case computation. Reviewing issues prior to building a Business case will ensure that the IT estate in your datacenter is represented more accurately.
