SP and tenants can run different versions of Veeam Backup & Replication on their Veeam backup servers. Veeam backup servers on the SP and tenant’s side must meet the following requirements:
- Veeam Backup & Replication versions must support the Veeam Cloud Connect functionality.
- The SP Veeam backup server must run the same or later version of Veeam Backup & Replication than tenant’s Veeam backup server. Veeam Backup & Replication supports 2 latest major versions for tenants’ Veeam backup servers.
If the SP or tenant plan to upgrade Veeam Backup & Replication, the upgrade process must start on the SP side. The upgrade process should be performed in the following way:
- The SP upgrades Veeam Backup & Replication on the SP backup server. The upgrade procedure does not differ from a regular one. To learn more, see the Upgrading to Veeam Backup & Replication 9.5 section in the Veeam Backup & Replication User Guide at: https://www.veeam.com/documentation-guides-datasheets.html.
- After Veeam Backup & Replication on the SP side is upgraded, the tenant can perform the same upgrade procedure on the tenant backup server.
- After upgrade to Veeam Backup & Replication 9.5, the tenant needs to upgrade backups that were created on the cloud repository with an earlier version of the product. To learn more, see Upgrading Cloud Backups.
Tenants who run earlier versions of Veeam Backup & Replication can continue using cloud resources provided to them by the SP who has upgraded Veeam Backup & Replication. However, some Veeam Cloud Connect functionality introduced in the current version of Veeam Backup & Replication may be not available to these tenants. For example, tenants who run Veeam Backup & Replication 9.0 cannot create backups on a scale-out backup repository exposed as a cloud repository. Parallel data processing is also not supported for such tenants.
