Upgrading Backup Proxy Servers

To communicate with backup proxy servers, Veeam Backup for Microsoft 365 uses the proprietary service — Veeam Backup Proxy for Microsoft 365 Service that is installed on the target proxy machine. When you upgrade Veeam Backup for Microsoft 365 to a newer version, this service becomes outdated and all backup proxies configured in your environment are marked as Out of Date and must be upgraded manually.

To upgrade backup proxy servers, do the following:

  1. Launch the Proxy Upgrade wizard.
  2. Select a backup proxy server to upgrade.
  3. Specify credentials.
