+## Validating the inventory of machines to migrate
+
+Identify the virtual machines (VMs) to migrate on your VMware plattform:
+
+- Disk configuration (number, size, type)
+- Network configuration (number of NICs, type)
+- Boot type (BIOS or UEFI)
+
+
+## Preparing a Scaleway Instance to manage the migration
+
+1. [Create a new instance](/instances/how-to/create-an-instance/) and log into it [using SSH](/instances/how-to/connect-to-instance/).
+2. Install the following CLI tools, required for the migration of your virtual machine:
+   - `qemu-img` — for converting VMDK to QCOW2
+      ```sh
+      apt install qemu-utils
+      ```
+   - `scw` — for Scaleway operations
+      ```sh
+      curl -s https://raw.githubusercontent.com/scaleway/scaleway-cli/master/scripts/get.sh | sh
+      ```
+   - `aws` — for uploading to S3
+      ```
+      curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
+      unzip awscliv2.zip
+      sudo ./aws/install
+      ```
+   - `govmomi` — for interacting with vCenter
+     ```
+     curl -L -o - "https://github.com/vmware/govmomi/releases/latest/download/govc_$(uname -s)_$(uname -m).tar.gz" | tar -C /usr/local/bin -xvzf - govc
+     ```
+
+3. Configure credentials for the tools:
+   - For Scaleway: `scw init`
+   - For AWS/S3: Refer to [Using Object Storage with the AWS-CLI](https://www.scaleway.com/en/docs/object-storage/api-cli/object-storage-aws-cli/)
+   - For vCenter: credentials and VPN (if needed)
+
+## Downloading VMDK files using govmomi
+
+Download the VMDK file from vCenter:
+
+```bash
+govc export.ovf -vm <vm_name>
+```
+
+<Message type="note">
+  Adjust this based on your `govmomi`/`govc` setup and environment.
+</Message>
+
+## Converting the VMDK file to QCOW2**
+
+Convert the downloaded VMDK file to QCOW2 using `qemu-img`:
+
+```bash
+qemu-img convert -O qcow2 <vm_name>.vmdk <vm_name>.qcow2
+```
+
+### (Optional): Mounting the QCOW2 file and system configuration
+
+1. Mount the QCOW2 image on your Instance:
+  ```bash
+  sudo modprobe nbd
+  sudo qemu-nbd -c /dev/nbd0 <vm_name>.qcow2
+  ```
+  Make any changes (e.g., install cloud-init, remove VMware tools).
+
+2. Unmount the file:
+
+```bash
+sudo qemu-nbd -d /dev/nbd0
+```
+
+## Uploading the QCOW2 image to Scaleway Object Storage
+
+Upload the converted disk:
+
+```bash
+aws s3 cp <vm_name>.qcow2 s3://<bucket_name>/
+```
+
+## Importing the QCOW2 image from Object Storage into Scaleway as a volume
+
+Import into a new volume:
+
+```bash
+scw instance volume import qcow2-from-s3 \
+  s3-url=s3://<bucket_name>/<vm_name>.qcow2 \
+  name=<volume_name> \
+  project-id=<project_id> \
+  zone=<zone>
+```
+
+> You can retrieve project ID and zone using `scw project list` and `scw zone list`.
+
+---
+
+### **Step 8: Create an image from the imported volume**
+
+```bash
+scw instance image create-from-volume \
+  volume-id=<volume_id> \
+  name=<image_name> \
+  zone=<zone>
+```
+
+---
+
+### **Step 9: Create Private Networks if needed**
+
+```bash
+scw vpc private-network create \
+  name=<pn_name> \
+  ipam-configs.0.cidr=<subnet_cidr>
+```
+
+---
+
+### **Step 10: Boot an instance with the image and attach PN**
+
+Create a new server:
+
+```bash
+scw instance server create \
+  name=<instance_name> \
+  image-id=<image_id> \
+  commercial-type=<type> \
+  zone=<zone> \
+  private-nics.0.private-network-id=<pn_id>
+```
+
+Start the server:
+
+```bash
+scw instance server start server-id=<server_id> zone=<zone>
+```
+
+---
+
+## ✅ Final Notes
+
+- Run `scw --help` or `scw instance server create --help` for more guidance.
+- Double-check your Scaleway **region/zone compatibility** (e.g., `fr-par-1`, `nl-ams-1`, etc.).
+- Ensure the image is cloud-ready: ideally includes `cloud-init`.
