+updated: 2025-04-25
+---
+
+## Objective
+
+This guide explains how to migrate your on-premises VMware workloads to an **OVHcloud Hosted Private Cloud (HPC)** using Veeam Replication.
+
+> [!primary]
+> **This guide applies to Hosted Private Cloud environments that are NOT part of SecNumCloud (SNC), PCI-DSS, or HDS-qualified environments.**
+> If you are using an SNC, PCI-DSS, or HDS-qualified Hosted Private Cloud, some features described here, such as OVHcloud IAM, may not be available.
+> For SecNumCloud environments, please refer to the dedicated guide: [Move2Cloud - Migrating VMware Workloads to SecNumCloud Hosted Private Cloud with Veeam Replication](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/vmware_migration_veeam_secnumcloud)
+
+## Requirements
+
+Before getting started, you will need:
+
+- A complete list of VMs with FQDNs, IP addresses, and dependencies.
+- Correctly sized target resources (e.g., hosts, datastores, vSAN clusters).
+- A valid **Veeam Backup & Replication** solution from the [Veeam website](https://www.veeam.com/downloads.html?ad=top-sub-menu).
+- Access to vCenter and pre-configured DNS, NTP, and authentication services in HPC.

+
+## Instructions
+
+### Step 1: Design your migration plan
+
+At the end of Step 1, you should have a clear understanding of which workloads you are migrating, their dependencies, and the target network and storage configuration in OVHcloud.
+
+#### Step 1.1: Create an inventory of VMs
+
+Start by listing all the VMs you plan to migrate.
+
+For each VM, include the following information:
+
+- **FQDN (Fully Qualified Domain Name)** and **IP address**.
+- **Operating System version** (ensure it’s up-to-date and supported).
+- **Dependencies** (e.g. applications relying on specific servers).
+
+#### Step 1.2: Group VMs into migration batches
+
+Organize your VMs into logical groups based on their application dependencies.
+
+For instance:
+
+- A **web server**, an **application server**, and a **database server** that work together should be grouped in the same batch.
+
+Migrating these batches ensures that applications remain functional during the transition.
+
+#### Step 1.3: Document network and subnet details
+
+Record the current network configuration of your on-premises environment, including:
+
+- **Subnets** and **VLAN IDs**.
+- The number of VLANs needed for the target Hosted Private Cloud.
+
+With [OVHcloud vRack](/links/network/vrack), you can create up to 4,000 VLANs, which allows you to replicate your current IP address plan without any re-IP.
+
+### Step 2: Plan target resources 
+
+At the end of this step, you will have a clear understanding of the resources required in your **Hosted Private Cloud (HPC)** environment to match your workloads.
+
+#### Step 2.1: Calculate compute requirements
+
+Evaluate your needs for CPU and memory by calculating the total number of cores and amount of RAM required for your VMs.
+
+Use your current consolidation ratio (e.g. pCPU/vCPU) as a reference to determine the number and type of ESXi hosts needed.
+
+#### Step 2.2: Define storage needs
+
+Decide which workloads require **NFS datastores** or **vSAN storage** based on their IOPS requirements. For applications with high performance demands, vSAN is typically the better option.
+
+#### Step 2.3: Plan the network
+
+If using NSX-T, define your network segmentation strategy. Determine how you will apply VLAN-based or overlay segments and evaluate north/south traffic.
+
+Decide whether to retain your current firewall solution or deploy virtual firewalls (e.g. FortiVM, Stormshield, or Palo Alto VM-Series).
+
+For internet-exposed services, allocate additional public IPs or use the [Bring Your Own IP (BYOIP)](/links/network/byoip) feature to retain your existing IP addresses.
+
+### Step 3: Authorize IP access to vCenter
+
+To enable remote access to the vCenter in your HPC, you must whitelist the IP addresses that need access.
+
+1. Log in to the [OVHcloud Control Panel](/links/manager).
+2. Navigate to the `Hosted Private Cloud`{.action} section and open the Secure SSL Gateway.
+3. Add the IP addresses that should have access to vCenter.
+
+You can find detailed instructions in our [IP whitelisting guide](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/autoriser_des_ip_a_se_connecter_au_vcenter).
+
+### Step 4: Configure roles and permissions
+
+#### Step 4.1: Use OVHcloud IAM
+
+Set up roles and permissions in your `Hosted Private Cloud`{.action} using `OVHcloud IAM`.
+
+> [!warning]
+> **OVHcloud IAM is not available in SecNumCloud (SNC), PCI-DSS, or HDS environments.**
+> If you are using one of these qualified environments, you must configure roles and permissions directly in vSphere or use an external IAM solution such as Microsoft Active Directory or Okta.
+
+For instructions, refer to the [IAM setup guide](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/vmware_iam_getting_started).
+
+#### Step 4.2: Integrate with existing IAM solutions
+
+If you already use an identity management system such as Active Directory or Okta, you can deploy these services within your HPC.
+
+#### Step 4.3: Enable single sign-on
+
+To simplify access, you can configure Single Sign-On (SSO) by linking `OVHcloud IAM` with your ADFS (Active Directory Federation Services).
+
+Follow the steps in [this guide](/pages/account_and_service_management/account_information/ovhcloud-account-connect-saml-adfs).
+
+### Step 5: Build your target network
+
+#### Step 5.1: Define the flow matrix
+
+Plan your network traffic by creating a flow matrix. Identify which VLANs are routed and which VMs should exchange traffic, specifying allowed ports and protocols.
+
+#### Step 5.2: Configure NSX-T
+
+Use NSX-T to configure Tier-1 and Tier-0 gateways, distribute traffic, and segregate workloads. VMware tenants come with preconfigured **distributed vSwitches (dVS)** and VLANs, which you can adjust to match your environment.
+
+Refer to the [NSX first steps guide](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/nsx-01-first-steps) for more details.
+
+### Step 6: Deploy core services
+
+Your Hosted Private Cloud requires basic infrastructure services for your migrated workloads:
+
+- **NTP:** Configure `ntp.ovh.net` for time synchronization.
+- **DNS:** Deploy DNS services, such as an Active Directory Domain Controller, to resolve domain names.
+- **Authentication:** Set up authentication services locally in HPC to minimize cross-environment traffic.
+
+### Step 7: Install the Veeam Backup & Replication server
+
+Install the **Veeam Backup & Replication (B&R)** server in your OVHcloud HPC environment. This server will handle the replication process.
+
+Activate its license using the [setup guide](/pages/storage_and_backup/backup_and_disaster_recovery_solutions/veeam/veeam_veeam_backup_replication).
+
+### Step 8: Set up secure connectivity
+
+#### Step 8.1: Configure a VPN tunnel
+
+Set up an IPsec tunnel between your on-prem infrastructure and OVHcloud using NSX, Stormshield, or OpnSense:
+
+- [NSX VPN setup](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/nsx-12-configure-ipsec)
+- [Stormshield VPN setup](https://documentation.stormshield.eu/SNS/v4/en/Content/User_Configuration_Manual_SNS_v4/IPSec_VPN/IPSEC_VPN.htm)
+- [OpnSense VPN setup](https://docs.opnsense.org/manual/how-tos/ipsec-s2s.html)
+
+#### Step 8.2: Use OVHcloud Connect (Optional)
+
+For higher bandwidth and lower latency, you can subscribe to [OVHcloud Connect](/links/network/ovhcloud-connect), which provides an MPLS-like link between your on-prem infrastructure and your OVHcloud tenant.
+
+With [OVHcloud Connect](/links/network/ovhcloud-connect), latency is controlled, and you can choose the bandwidth you need, from 200 Mbps up to several Gbps.
+
+### Step 9: Deploy the Veeam proxy server
+
+A Veeam proxy server must be deployed in your on-prem infrastructure to manage data transfer.
+
+1. Add the proxy server in the Veeam Console under **Backup Infrastructure**.
+2. Configure transport modes and resource allocation.
+
+Follow the [proxy setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/add_vmware_proxy.html?ver=120) for a detailed walkthrough.
+
+### Step 10: Create replication jobs
+
+In **Veeam Backup & Replication**, create a replication job to migrate your VMs.
+
+1. Open the `Replication Jobs`{.action} section in the Veeam Console.
+2. Add the `source VMs`{.action} and configure the target HPC environment.
+3. Set additional options like compression or application-aware processing.
+
+Detailed steps are available in the [replication job setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/replica_job.html?ver=120).
+
+### Step 11: Start and test replication
+
+Run your replication jobs and test their functionality using Veeam’s `Failover Now`{.action} feature. Revert to the original state using `Undo Failover`{.action}.
+
+Refer to the [Failover process](https://helpcenter.veeam.com/docs/backup/vsphere/failover.html?ver=120) and [Undo Failover process](https://helpcenter.veeam.com/docs/backup/vsphere/undo_failover.html?ver=120).
+
+### Step 12: Finalize migration
+
+Perform a `Planned Failover`{.action} on migration day to synchronize final changes, power off the source VMs, and activate the replicas in HPC.
+
+See the [Planned Failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/planned_failover.html?ver=120).
+
+### Step 13: Validate applications
+
+Ensure all VMs boot successfully and test critical services like AD, DNS, and databases to confirm full functionality.
+
+### Step 14: Confirm permanent failover
+
+Use the `Permanent Failover`{.action} option in Veeam to finalize your migration. This will make the replicas in HPC the primary production VMs.
+
+Refer to the [Permanent Failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/permanent_failover.html?ver=120).
+
+### Step 15: Optimize and secure
+
+Move VMs to target storage using [Storage vMotion](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/vmware_storage_vmotion) and configure backup jobs in [OVHcloud Object Storage](/links/public-cloud/object-storage) to protect your workloads.
+
+### Step 16: Move VMs to target storage
+
+Once your VMs have been migrated to the OVHcloud HPC, you may need to optimize their location within the environment based on performance requirements.
+
+This involves moving VMs and their virtual disk files (VMDKs) to the appropriate storage.
+
+1. **Assess Performance Requirements:**
+    - Identify which VMs require high-performance storage (e.g. vSAN for intensive workloads).
+    - Use NFS datastores for less demanding applications.
+2. **Use Storage vMotion:**
+    - Open the `vSphere Client`{.action} and navigate to the VM you wish to move.
+    - Right-click the VM and select `Migrate`{.action}.
+    - Choose the `Change storage only`{.action} option and select the target datastore (vSAN or NFS).
+    - Review and confirm the migration settings, then start the migration process.
+
+This step ensures your VMs are stored on the appropriate infrastructure to meet their performance needs.
+
+For more information, refer to the [Storage vMotion guide](/pages/hosted_private_cloud/hosted_private_cloud_powered_by_vmware/vmware_storage_vmotion).
+
+### Step 17: Create backup jobs to secure your workloads
+
+Now that your VMs are running in the OVHcloud Hosted Private Cloud, it’s essential to establish a backup strategy to protect your data.
+
+**Veeam Backup & Replication** provides flexible options for securing your workloads.
+
+1. **Define Backup Storage:**
+    - Use OVHcloud **[S3*-compatible Object Storage](/links/public-cloud/object-storage)** as a backup repository for scalability and cost efficiency.
+2. **Create a Backup Job in Veeam:**
+    - Open the **Veeam Console** and navigate to the `Home`{.action} tab.
+    - Click `Backup Job`{.action} > `Virtual Machine`{.action} and follow the wizard:
+    - Select the VMs to back up.
+    - Choose the backup repository (e.g. OVHcloud Object Storage).
+    - Configure retention policies, compression, and encryption settings.
+3. **Run and Test the Backup Job:**
+    - Start the backup job and monitor its progress.
+    - Perform a test restore to ensure the backups are reliable and can be used in a recovery scenario.
+
+Setting up regular backups guarantees that your workloads are protected against data loss or corruption. For detailed instructions, refer to the [Veeam S3 backup guide](/pages/storage_and_backup/object_storage/s3_veeam).
