This overview outlines the general steps required for migrating VMs from AWS EC2 to Google Cloud Platform (GCP) using Google Cloud Migrate for Compute Engine (formerly Velostrata).
Before beginning a migration to GCP, you must create Cloud Identity and Access Management permissions.
Set up a VPN
Plan for and create a secure connection between AWS and GCP. One way to do so is to use Terraform to create one.
Set up AWS Networks
See Network Access Requirements for detailed information on firewall, routing and network tag considerations for your Migrate for Compute Engine deployment.
Create AWS IAM credentials
Create IAM groups and credentials that will enable the Migrate for Compute Engine to connect to AWS.
Set up the Velostrata Manager
The Velostrata Manager provides a web UI and controls migration operations from GCP. Set it up to continue.
Upload the AWS IAM credentials to Velostrata Manager
Next, create Cloud Details on your Velostrata Manager using your AWS IAM credentials.
Create Cloud Extensions
After configuring the Velostrata Manager and Velostrata Backend, create Cloud Extensions for your migration.
Prepare your Linux VMs
If you are migrating Linux VMs, install the Migrate for Compute Engine package to reconfigure them for GCP.
