Upgrading to Arcserve UDP Version 6.0 › Backward Compatibility Support Policy

Backward Compatibility Support Policy

Important! You may face data corruption for backward compatibility of protecting Arcserve UDP v5 nodes to Arcserve UDP v6 RPS on the deduplication data store. To avoid, refer to the Known Issue on Backward Compatibility Related before performing an upgrade.

We recommend upgrading all components to Arcserve UDP Version 6.0 in the entire environment so that new features in Arcserve UDP Version 6.0 can work properly. The existing backup plans are not impacted if the upgrade does not complete for all the components at the same time.

Backward Compatibility Support Arcserve UDP Version 5.0 Update 4, Update 3, and Update 2

Backward Compatibility Support for Windows RPS / Agent (or agentless backup proxy)

• Arcserve UDP Version 6.0 Console support recovery point servers (RPS) and Agents (or agentless backup proxies) of the previous versions for backup if the plan does not change after an upgrade.
• Arcserve UDP Version 6.0 Console and RPS support previous versions of Agents (or agentless backup proxies) for backup if the plan does not change after an upgrade.
• Arcserve UDP Version 6.0 Console supports adding a previous version of RPS server, but the RPS is automatically upgraded to Arcserve UDP Version 6.0 when it is added (no reboot required after the auto-upgrade).
• Arcserve UDP Version 6.0 Console supports adding a previous version of Agent (or agentless backup proxy) without automatically upgrading the Agent.
  • However, when a plan is modified and saved, the Agents (or agentless backup proxies) associated is automatically upgraded (no reboot required after the auto-upgrade).
  • And when a node is being updated, the Agent (or agentless backup proxy) is automatically upgraded (no reboot required after the auto-upgrade).
• After upgrading the Console, the existing plans continue to run on the previous versions of RPS, which is managed by this Console.
  • If you create a new plan, you cannot specify the previous version of the RPS, which is already managed by this Console, as the destination until the RPS is upgraded.
  • If you modify an old plan, the plan cannot be saved if the destination is a previous version of the RPS, which is managed by this Console, until the RPS is upgraded.
• Replication is supported from Arcserve UDP Version 5.0 Update 3 or Update 4 to Arcserve UDP Version 6.0 target RPS
  • However, If you replicate from Arcserve UDP Version 5.0 GM, Update 1, or Update 2 to Arcserve UDP Version 6.0 target RPS, the replication jobs fail.
  • Replication is not supported from Arcserve UDP Version 6.0 to any lower version target RPS, including Arcserve UDP Version 5.0 GM, Update 1, Update 2, Update 3, or Update 4
• Virtual Standby backward compatibility policy:
  • VSB Monitor version should be similar to the Agent version, if the backup destination is a shared folder.
  • VSB Monitor version should be similar to the RPS version, if the backup destination is RPS.

Backward Compatibility Support for Linux Backup Server

• Arcserve UDP Version 6.0 Console does not support any previous Linux Backup Server after an upgrade. You must upgrade the Linux Backup Server to the same version as the Console. If you do not upgrade the Linux Backup Server, you cannot create or modify nodes and plans.
• Arcserve UDP Version 6.0 Console does not support adding a previous version of the Linux Backup Server. You must upgrade the Linux Backup Server to the same version as the Console.
• After you upgrade the Linux Backup Server, BMR and File-level restore for older recovery points are supported.
