+excerpt: "Learn how to migrate your on-prem VMware workloads to an OVHcloud Hosted Private Cloud environment using Veeam Replication."
+updated: 2025-01-28
+---
+## Objective
+
+This guide outlines the steps to migrate your on-premises VMware workloads to an OVHcloud Hosted Private Cloud (HPC) using Veeam Replication. It walks you through migrating your workloads smoothly with as little downtime as possible.
+
+## Requirements
+
+Before getting started, make sure you have the following:
+
+1. **Prepare your source environment:**
+   - A complete list of VMs with FQDNs and IP addresses.
+   - Updated operating systems and mapped dependencies.
+   - Subnets and VLAN IDs for planning your network.
+
+2. **Prepare the target environment:**
+   - Correctly sized resources (hosts, datastores, vSAN clusters).
+   - A Hosted Private Cloud with NSX-T and VLANs, if needed.
+   - A valid Veeam Backup & Replication (B&R) license.
+
+3. **Network setup:**
+   - A VPN tunnel or OVHcloud Connect (optional) for secure communication.
+
+4. **Core services and tools:**
+   - Access to vCenter.
+   - Pre-configured DNS, NTP, and authentication services in HPC.
+
+5. **Access to documentation:**
+   - Relevant OVHcloud and Veeam guides for configuration details.
+
+## Instructions
+
+### 1. Inventory Source VMs and Network Configuration
+- List all VMs with their FQDNs, IP addresses, operating systems, and dependencies.
+- Group VMs by application to reduce service interruptions during migration.
+- Document subnets and VLAN IDs for replication planning.
+
+### 2. Size Target Resources
+- Calculate your needs for cores, RAM, and storage.
+- Decide on storage types (NFS or vSAN) based on performance requirements.
+- Plan VLAN routing and network segregation with NSX-T if needed.
+
+### 3. Whitelist IPs for vCenter Access
+- Allow required IPs to access the vCenter through the OVHcloud Secure SSL Gateway.
+- Follow the [guide to whitelist IPs](https://help.ovhcloud.com/csm/en-gb-vmware-authorise-ip-addresses-vcenter?id=kb_article_view&sysparm_article=KB0045321).
+
+### 4. Set Up Roles and Permissions
+- Mirror roles and permissions from your current environment in HPC.
+- Use OVHcloud IAM or integrate your existing IAM (e.g., Active Directory, Okta).
+- Enable SSO via ADFS using [this guide](https://help.ovhcloud.com/csm/en-gb-connect-saml-sso-adfs?id=kb_article_view&sysparm_article=KB0043008).
+
+### 5. Build Your Target Network
+- Set up VLANs, routing, and traffic flow matrices in NSX-T.
+- Configure dVS and NSX-T gateways for network segregation and filtering.
+- Check the [NSX first steps guide](https://help.ovhcloud.com/csm/en-gb-vmware-nsx-first-steps?id=kb_article_view&sysparm_article=KB0056831).
+
+### 6. Deploy Core Services in HPC
+- Deploy services like NTP, DNS, and authentication to reduce cross-traffic.
+- Use `ntp.ovh.net` for time synchronization.
+- Set up DNS services, such as an AD Domain Controller.
+
+### 7. Install Veeam B&R Server
+- Install Veeam Backup & Replication on your OVHcloud HPC.
+- Activate the license using [this guide](https://help.ovhcloud.com/csm/en-gb-public-cloud-storage-veeam-backup-replication?id=kb_article_view&sysparm_article=KB0046503).
+
+### 8. Configure a VPN Tunnel
+- Create an IPsec tunnel between your on-prem infrastructure and OVHcloud.
+- Use NSX, Stormshield, or OpnSense for the configuration:
+  - [NSX VPN setup](https://help.ovhcloud.com/csm/en-gb-vmware-nsx-configure-ipsec?id=kb_article_view&sysparm_article=KB0058696)
+  - [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)
+- Or use [OVHcloud Connect](https://www.ovhcloud.com/fr/network/ovhcloud-connect/) for low-latency and high bandwidth.
+
+### 9. Deploy Veeam Proxy Server
+- Set up a Veeam proxy on your on-prem infrastructure.
+- Verify connectivity with the Veeam B&R server in the HPC.
+- Follow the [proxy setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/add_vmware_proxy.html?ver=120).
+
+### 10. Create Replication Jobs
+- Use the Veeam B&R server to define replication jobs.
+- Follow the [replication job setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/replica_job.html?ver=120).
+
+### 11. Start and Test Replication Jobs
+- Start replication jobs and monitor their progress.
+- Run a pre-test with Veeam’s failover function to check replication without affecting source VMs:
+  - [Failover process](https://helpcenter.veeam.com/docs/backup/vsphere/failover.html?ver=120)
+  - [Undo failover process](https://helpcenter.veeam.com/docs/backup/vsphere/undo_failover.html?ver=120)
+
+### 12. Migrate Workloads
+- Perform a planned failover to turn off on-prem VMs, replicate any final changes, and power on the VMs in HPC.
+- Check the [planned failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/planned_failover.html?ver=120).
+
+### 13. Validate Applications and Services
+- Confirm VMs boot without issues.
+- Test connectivity to services like AD, DNS, and internet-facing apps.
+- Verify that all applications are working correctly.
+
+### 14. Confirm Permanent Failover
+- Finalize the migration by using the permanent failover action:
+  - [Permanent failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/permanent_failover.html?ver=120).
+
+### 15. Optimize and Secure Your Environment
+- Move VMs to the desired storage (e.g., vSAN or NFS datastores) using [Storage vMotion](https://help.ovhcloud.com/csm/fr-vmware-storage-vmotion?id=kb_article_view&sysparm_article=KB0046287).
+- Create backups for your workloads with OVHcloud S3 storage as described [here](https://help.ovhcloud.com/csm/fr-public-cloud-storage-s3-veeam?id=kb_article_view&sysparm_article=KB0047499).
