Installation notes

Upgrading the Cyber Protection agent

The Cyber Protection agent can be updated directly to Acronis Cyber Protect 17 from any version of Acronis Cyber Protect 15 or 16.

Updating the Management server (MMS)

The Acronis Management Server can be updated directly to Acronis Cyber Protect 17 from any version of Acronis Cyber Protect 16. If you are using Acronis Cyber Protect 15 management server, you must upgrade it to 16 first, and then upgrade to 17.

Important

  • Updating from older builds requires an active subscription license or support maintenance agreement. Verify that you have a valid subscription license or support maintenance agreement before you initiate an upgrade.

  • If you are using BitLocker on protected workloads, suspend or disable BitLocker before updating the Cyber Protection Agent. After the update, enable BitLocker again. If you fail to disable BitLocker before the update, the BitLocker recovery key will be required after you restart the workload. See product documentation.
  • If you plan to use the immutable storage functionality, see Updating the Account Server certificate.
  • If you plan to use Virtual Host/Universal licenses for protection of virtual machines by running a protection agent inside them (agent-based backup), see this knowledge base article.
