Veeam Backup & Replication Upgrade Paths KB ID: 2053 Product: Veeam Backup & Replication | 10 | 11 | 12 | 12.1 | 12.2 | 12.3 | 12.3.1 | 12.3.2 | 13 | 13.1 Published: 2015-07-10 Last Modified: 2026-09-15 Languages: JP Tenants of Veeam Cloud Service Providers If your Veeam Backup & Replication installation is connected to a Veeam Cloud Service Provider, contact your Service Provider before upgrading to ensure that the intended upgrade will not break compatibility. A tenant cannot be on a newer version of Veeam Backup & Replication than the Service Provider. Purpose This article documents upgrade paths available to Windows-based Veeam Backup & Replication deployments to reach the latest version. Solution End of Support Upgrade Path If you are using a version of Veeam Backup & Replication (VBR) that has reached its End of Support (EOS) and cannot be directly upgraded to a supported version, you will need to install a new instance of VBR using the latest VBR version . Clarification: If the Upgrade Instructions in the User Guide for a currently supported version of VBR include an upgrade path from an older, unsupported version, this upgrade pathway is still considered supported. This article provides details on upgrade processes for such situations, provided that a currently supported version of VBR supports a direct upgrade from these older versions. For example: When VBR version 11a was supported, it provided an upgrade path from VBR version 9.5 Update 4b. However, VBR version 12 does not support upgrading directly from 9.5 Update 4b. As a result, after VBR 11a reached EOS, the upgrade path for 9.5 Update 4b was removed from this document. VBR version 12.0, which is currently supported, allows upgrading directly from VBR version 10a. Thus, although VBR 10a is no longer supported itself, the upgrade details for 10a are included in this document because an upgrade to VBR 12.0 from that version is officially supported. VSA Migration Version Limitation Please note that deployment migration from Windows-based Veeam Backup & Replication to the new Linux-based Veeam Software Appliance is supported only for version 13.0.x builds. Customers who plan to migrate deployments should remain on 13.0.3 until after the migration is completed. More Information: KB4800: Veeam Backup & Replication Platform Migration Guide (Windows to Linux) Veeam Backup & Replication 13.0.3.63 remains available from the Previous Versions download page . The upgrade paths shown below for 13.1 are the same for 13.0. 10a to 13.1.1 Path: 10a (10.0.1.x) → 12.0 → 12.3.2 → 13.1.1 Upgrade to Veeam Backup & Replication 12.0 Note: It is necessary to first upgrade to Veeam Backup & Replication 12.0 to allow components such as Veeam Backup for Nutanix AHV Proxy to be upgraded to a version that is compatible with being upgraded to the version included with Veeam Backup & Replication 12.3.2. Upgrade to Veeam Backup & Replication 12.3.2 Upgrade to Veeam Backup & Replication 13.1.1 11 to 13.1.1 Path: 11 (11.0.0.x) → 12.0 → 12.3.2 → 13.1.1 Upgrade to Veeam Backup & Replication 12.0 Note: It is necessary to first upgrade to Veeam Backup & Replication 12.0 to allow components such as Veeam Backup for Nutanix AHV Proxy to be upgraded to a version that is compatible with being upgraded to the version included with Veeam Backup & Replication 12.3.2. Upgrade to Veeam Backup & Replication 12.3.2 Upgrade to Veeam Backup & Replication 13.1.1 11a to 13.1.1 Veeam Backup & Replication 11a Upgrade Path Notes If the Veeam Backup & Replication 11a deployment does not interact with Nutanix AHV , it can be upgraded directly to the latest version 12.3 release, skipping version 12.0. If Veeam Backup & Replication 11a P20240304 is installed, it is only compatible with upgrading to version 12.1.2 or higher (such as 12.3). Upgrading to version 12.0 is not supported. Path: 11a (11.0.1.x) → 12.0 → 12.3.2 → 13.1.1 Upgrade to Veeam Backup & Replication 12.0 Note: It is necessary to first upgrade to Veeam Back
