Migration Center discovery client CLI overview

The Migration Center discovery client CLI (mcdc CLI) is an offline tool that lets you run different types of asset discoveries on your infrastructure. These asset discoveries scan the physical servers, virtual machine (VM) instances, and databases (Preview) in your infrastructure to collect the necessary information for a successful migration assessment to Google Cloud.

Migration Center provides advanced migration recommendations and planning capabilities, however, if you're working with sensitive data and don't want to upload it to Google Cloud, you can choose to run an offline assessment instead.

The mcdc CLI has the following advantages:

  • It doesn't require installation.
  • It runs on Linux and Windows host machines.
  • It creates offline assessment reports.

You can use the data collected by running a mcdc CLI discovery to perform the following actions:

Available collection methods

Using the mcdc CLI, you can run the following collection methods:

  • Inventory discovery scans and lists all of the VMware VM instances, Amazon Elastic Compute Cloud (EC2) instances (Preview), Amazon Relational Database Service (RDS) (Preview), and Azure Virtual Machine instances (Preview).
  • Guest discovery scans VM instances and physical servers, collecting data about the running applications. This data includes information about machine configurations, hardware, network, open files, services, and processes. Guest discovery also scans and lists Microsoft SQL Server, PostgreSQL, and MySQL databases that are running on-premises and on AWS (Preview).
  • IP range scan detects all assets in your network, verifies credentials, and scans the detected assets. It collects data using guest discovery. Use IP range scan when you have several machines in an IP address range or when you are unfamiliar with the infrastructure that you want to scan.

Limitations

  • The mcdc CLI can export data of only up to 10,000 machines to Migration Center.
