Installing the Migrate Connector

"Migration isn't complicated if you keep in mind the below points"

To migrate virtual machines (VMs) from an on-premises data center to Google Cloud, you must first configure a migration source that specifies the data center from which you’ll be migrating the VMs. To configure a migration source, install and configure the Migrate Connector on your vSphere data center. Once installed, the Migrate Connector establishes a secure connection between the on-premises environment and the Google Cloud using Google Cloud APIs over port 443. Migration traffic can be routed over public internet, VPN, Private Google Access, or Dedicated interconnect. The Migrate Connector performs storage operations against VM disks using the vSphere APIs and queries on-premises VM inventory so that you can use the Google Cloud console to browse the VMs on the data center available for migration. The Migrate Connector also stops and monitors source VMs using vSphere APIs when performing cut-over.

Before you install and register the Migrate Connector, ensure that you have enabled Migrate to Virtual Machines on Google Cloud and that your hardware meets the following requirements:

* 4 CPUs with Instruction Set Architecture (ISA) compatibility to Westmere (microarchitecture) CPU or higher

* 16 GB of RAM

* 30 GB of datastore space

You can install the Migrate Connector Open Virtualization Format (OVA) by using the vSphere user interface (UI) or the VMware OVF Tool (ovftool) command-line interface (CLI).
