Install the Exoscale command line interface on your PC or another server

Install the Exoscale CLI, more details can be found here:

Configuration information can be found here: https://community.exoscale.com/documentation/tools/exoscale-command-line-interface/

  • To create a key, click on “IAM” on the left side and create a “restricted” key for the “Compute” service


Save the key and the secret (Please do not share with third parties)

Create a new instance with this template on Exoscale

  • Log in to Exoscale at portal.exoscale.com
  • Go to Compute -> Instances -> Add
  • For Template, select Windows Server 2016
  • Disk space should be at least the same size on Exoscale as on your old server!

Setting the firewall on Exoscale is not in the scope of this document. More information can be found here: https://community.exoscale.com/documentation/compute/security-groups/

You can use the “Default” Security Group or create your own. To configure the firewall correctly, be sure to allow access via RDP.

In addition, the following ports must be enabled for the transmission of data from ACRONIS:

Ingress TCP 443, 7700-7800, 44445, 8443.

Here you can see an example of a correct configuration:

Optional: add the IP Addresses column to distinguish between your instances and select your Exoscale instance as the destination.

  • You do not need to change any other settings
  • Select the Exoscale target server and disk here.
  • ATTENTION: If your original system has two partitions, Disk2 of the existing server will be restored in one of the next steps, skip the message in the ACRONIS portal which indicates this.
