The physical machines, VMs, and databases that discovery client 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 discovery client to each asset
- An account with administrator rights to the operating system
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 with support for the following encryption algorithms:
- RSA and DSA in PEM format
- ECDSA 256/384/521, ED25519 in OpenSSL or PEM formats
- Open line of sight from discovery client 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 discovery client to vCenter
- Read level access to vCenter
Databases
To collect data from your databases, the following requirements need to be met:
- The discovery client 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.
