You're viewing documentation for a prior version of Migrate for Compute Engine (formerly Velostrata). You can continue using this version, or use the current version.

Deploying the Velostrata Backend

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

The Velostrata On-Premises Backend virtual appliance connects to VM disks in your on-premises data center and streams or migrates them to Google Cloud using Cloud Extensions.

The Velostrata Backend is distributed as an Open Virtualization Format (OVF) package.

Sizing a VM for the Velostrata Backend

The Velostrata Backend requires the following, based on the number of VMs to be migrated concurrently:

Migration Size Resources
<=100 concurrent migrating VMs 2 vCPU, 4GB RAM
>100 concurrent migrating VMs 4 vCPU, 8GB RAM

Deploying and configuring the Velostrata Backend

  1. Download the Velostrata Backend OVA file, available from the Downloads page. You can verify the integrity of the files using the Velostrata Backend sha256 available from the Downloads page.
  2. Sign in to vSphere via the Flash Web Client.

  3. Right-click a parent object of one of the VMs to be migrated (such as a datacenter) and select Deploy OVF Template.

  4. Select the Migrate for Compute Engine OVA file.

  5. Choose the Host/ Cluster in your vSphere datacenter where you want to run the Velostrata Backend.

  6. Select a Disk Format, and click Next.

  7. Select the Network information that will host the Velostrata Backend. Click Next.

  8. Expand the Migrate for Compute Engine Backend Configuration section.

  9. Paste the token you copied from the Velostrata Manager on Google Cloud into Migrate for Compute Engine Backend Token.

    Note that this token includes the IP address of the Velostrata Manager so that the Velostrata Backend can access it.

  10. Enter and confirm a Password for the admin user on the Velostrata Backend. After installation, the password should be changed by connecting to the Velostrata Backend using SSH as admin and using the passwd command.

  11. Expand the Networking Properties section. Enter the Hostname for the Virtual Appliance. Enter a static IP Address, Netmask, Default Gateway, and DNS server for the Velostrata Backend. You can change these properties at any time later, but you must reboot the Virtual Appliance afterward in order for the changes to take effect.

  12. If you want to use an HTTP proxy for metrics and log uploads to Google Cloud's operations suite, fill in the HTTP Proxy parameter.

  13. If your VPN to Google Cloud is not configured with dynamic routing, you can enter the Static network route to reach subnets on Google Cloud. The address is in the form x.x.x.x/x y.y.y.y, where x.x.x.x/x is the Google Cloud VPC network address in CIDR format and y.y.y.y is the on-premises VPN Gateway IP address.

  14. Click Next and review the Ready to complete page.

  15. Click Finish. The Deploy OVF template task appears.

Configuring the Migrate for Compute Engine Service Role and Permissions in vCenter

Deploying the Migrate for Compute Engine VMware vCenter Plugin

Once the Velostrata Backend has successfully connected and registered with the Velostrata Manager on Google Cloud, you need to register and deploy the Migrate for Compute Engine VMware vCenter Web Client Plugin. This enables Migrate for Compute Engine management operations and monitoring in the vCenter UI.

  1. Make sure that a Migrate for Compute Engine vCenter Service Account (user) and Role have been created before proceeding.
  2. Sign in to your Velostrata Manager.
  3. Click the System Settings icon.
  4. If the Velostrata Backend is able to connect to the Velostrata Manager, the IP for the backend appears with a status of Registered and Connected.
