Requirements for machines and databases scanned

Stay organized with collections Save and categorize content based on your preferences.

The physical machines, VMs, and databases that Migration Center Collector collects data from are referred to as target assets in Google Cloud Migration Center. This page describes the specific configurations that the target assets must have, depending on the asset type and the collection method.

Windows machines

You can scan your physical or virtual Windows machines with the OS scan method. Windows machines must meet the following requirements:

  • WMI (Windows Management Instrumentation) Service running
  • Windows Firewall disabled. Alternatively, a firewall exception to allow for Remote WMI
  • Open line of sight from Migration Center Collector to each asset
  • An account with administrator rights to the operating system

To enable data collection for the modernization assessment, do the following:

  • Enable WinRM on the target server, or via Group Policy Object (GPO).
  • Enable PSRemoting on the target server.
  • Allow the following TCP inbound ports:
    • For Windows Server 2008 R2 and newer: HTTP 5985 and HTTPS 5986.
    • For Windows Server 2008 and older: HTTP 80 and HTTPS 443.

For more information on how to use the data that Google Cloud Migration Center collects for your assessment, see the documentation for modernization assessment.

Linux machines

You can scan your physical or virtual Linux machines with the OS scan method. Linux machines must meet the following requirements:

  • SSH enabled
  • Open line of sight from Migration Center Collector to each asset
  • An account with user-level access (no sudo or root privileges required)

VMware machines

If you cannot run an OS scan using Windows or Linux credentials, you can use a vCenter scan with vCenter credentials.

In this case, the minimum requirements are the following:

  • vCenter 5.5 or higher
  • Open line of sight from Migration Center Collector to vCenter
  • Read level access to vCenter

Databases

To collect data from your databases, the following requirements need to be met:

  • Migration Center Collector requires an open line of sight to each database.
  • For Oracle 12c and above, run the permission script available on GitHub before starting data collection.
  • For all non-Oracle databases, use an account with administrator rights to the database.
