veeam-backup-and-replication-v13-upgrade-01

When planning the Veeam v13 upgrade, it is important to consider not only the new capabilities but also the features and operating systems that are no longer supported.

As a best practice, perform a deep analysis of your configured backup infrastructure before beginning the Veeam v13 upgrade. This helps to identify potential issues that could cause service disruption due to compatibility problems or discontinued features.

 

System Requirements

Before upgrading to version 13, be aware that the new version introduces changes in backup management and some features have been deprecated or discontinued.

  • VMware vSphere support - the minimum supported version for VMware ESXi and VMware vCenter is 7.0.
  • Managed Hardened Repository v2managed hardened repository v2 is still supported but must be upgraded using the Veeam Virtual Infrastructure Appliance to continue receiving security updates.
  • Deprecated features:
    • Restore point retention is no longer available for new Backup Jobs.
    • Reversal incremental backup mode is no longer available for new Backup Jobs.
    • Single storage backup format is no longer available in the repository settings.
    • Active Directory authentication is no longer available for Veeam Cloud Connect tenants.
  • Discontinued features:
    • U-AIR wizard.
    • Initiating restore by double clicking VBK/VBM in Windows Explorer.
    • Burning Recovery Media to CD/DVD media.
  • Managed servers running unsupported OS - remove any managed server running an unsupported OS from the backup infrastructure.
  • Trusted host hardening - after upgrading to v13 verify that all servers in the backup infrastructure are trusted because as the remote host trust is set to Manual.
  • Application-aware image processing - Windows 7 and Windows 8.x are no longer supported. The minimum supported version are Windows 10 1507 LTSB/LTS, Windows 10 22H2 e Windows 11 22H2.
  • Agent Backup Jobs running on unsupported OS - agents running on unsupported OS won't be upgraded and will stop receiving new features.
  • Certificates - review the list of required Trusted Root Certificates and ensure all are installed.

 

Veeam v13 upgrade procedure

Before beginning the Veeam v13 upgrade procedure, keep the following in mind:

  • Upgrade path - a direct upgrade is supported if the installed version is 12.3.1 (build 12.3.1.1139) or later.
  • License format - Veeam Backup & Replication 13 uses the same license file format introduced with version 10.
  • Veeam Backup for Microsoft 365 - if  Veeam Backup & Replication and Veeam Backup for Microsoft 365 are installed on the same machine, upgrade Veeam Backup for Microsoft 365 first.
  • Veeam ONE - if this application is used to monitor the backup infrastructure, upgrade Veeam ONE first. The new version supports monitoring version 12 or later.
  • Veeam Backup Enterprise Manager - if installed, upgrade this component before upgrading Veeam Backup & Replication.
  • Scale-Out Backup Repositories - all immutable performance extents must have the same immutability settings.
