This is a sizing tool that uses a usage profiler, which is a data-gathering tool that helps you describe your projected or current usage of a Microsoft D365FO implementation.

The usage profile that is generated can be used for various purposes, such as hardware sizing for a production environment by Microsoft and support.

This tool seeks information in the following three sections:

• Deployment details
• Instance characteristics
• Retail and commerce

The Microsoft Dynamics Lifecycle Services subscription estimator provides an automated estimate of the subscription that's needed for your Microsoft D365FO instance. It does the following:

• It uses the user license details and the transaction count to infer the subscription's needs.
• There can be multiple versions of estimates and one of them can be marked as active, which in turn is used by Microsoft for production sizing purpose support.

Now, let's go through an important tool that we can use to pull resources to your LCS project.
