Backward Compatibility Support Policy for Arcserve UDP Version 8.x

Backward Compatibility Support between different UDP Console through the Replicate to a remotely-managed RPS task

If you plan to perform the Replicate to a remotely-managed RPS task, we recommend to upgrade the Console and RPS at destination before upgrading the Console / RPS / Agent at source.

• Replication is supported if the source RPS has UDP 9.2, while the destination RPS still has version UDP 9.1, 9.0, 8.x, and 7.0 Update 2.
• Replication is supported if the source RPS has version UDP 9.1, 9.0, 8.x, and 7.0 Update 2, and the destination RPS has UDP 9.2.
• Replication behaviors:
• If you upgrade to UDP 9.2 on both sites, replicate from Cloud Hybrid to on-premises without using a public IP.
• If you upgrade to UDP 9.2 only on one of the sites and the other site uses a supported version of UDP, such as:
• UDP 7.0 Update 2 - Replicate from Cloud Hybrid to on-premises using the public IP.
• UDP 8.x - Replicate from Cloud Hybrid to on-premises without using the public IP.

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

• Arcserve UDP 9.2 Console supports recovery point servers (RPS) and Agents (or agentless backup proxies) of version UDP 9.1, 9.0, 8.x, and 7.0 Update 2 for backup if the plan does not change after an upgrade.
• Arcserve UDP 9.2 Console and RPS support Agents (or agentless backup proxies) of version UDP 9.1, 9.0, 8.x, and 7.0 Update 2 for backup if the plan does not change after an upgrade.
• Arcserve UDP 9.2 Console supports Deploying existing plan without any changes when RPS and Agents (or agentless backup proxies) are still running on version UDP 9.1, 9.0, 8.x, and 7.0 Update 2. Agent is not automatically upgraded.

• Arcserve UDP 9.2 Console support actions such as Pause or Resume existing plan without any modification when RPS and Agents (or agentless backup proxies) are still running on the version UDP 9.1, 9.0, 8.x, and 7.0 Update 2. Agent is not automatically upgraded.
• Arcserve UDP 9.2 Console supports Creating new plan or modifying existing plan to configure legacy features that was supported already in the previous release when RPS and Agents (or agentless backup proxies) are still running on version UDP 9.1, 9.0, 8.x, and 7.0 Update 2. Agent is not automatically upgraded.
• Arcserve UDP 9.2 Console supports Creating new plan or Modifying existing plan to include UDP 9.2 new features when associated RPS, Proxy or Agent are already upgraded to expected version.
• For example:
• Specify Network for backup is supported when Console, RPS, Proxy and Agent are upgraded to UDP 7.0 Update 2, 8.x, 9.0, 9.1, and 9.2.
• Arcserve UDP 9.2 Console supports Update Node when RPS and Agents (or agentless backup proxies) are still running on version UDP 9.1, 9.0, 8.x, and 7.0 Update 2. Plan will be deployed. Agent is not automatically upgraded.
• Arcserve UDP 9.2 Console supports adding a version UDP 9.1, 9.0, 8.x, and 7.0 Update 2 of RPS server. But, the RPS is not automatically upgraded to Arcserve UDP version 9.2 when added.
• Arcserve UDP 9.2 Console supports adding a previous version of Agent (or agentless backup proxy) without automatically upgrading the Agent.
• Arcserve UDP 9.2 Console supports adding node to existing plan.
• Adding clean node to the existing plan is supported when associated RPS upgrades to UDP 9.2. Otherwise, plan is saved but plan deployment fails.
• Adding previous version node to the existing plan is supported if the version is similar to the running RPS version. Agent is not automatically upgraded.
• Adding Arcserve UDP 9.2 node to the existing plan is supported when associated RPS upgrades to UDP 9.2.
• Gateway is automatically upgraded to match the version of Arcserve UDP Console.
• Replication backward compatibility policy:
• Replication is supported when Console is upgraded to Arcserve UDP 9.2 but all the associated Recovery Point servers (RPSs) are still running on UDP 9.1, 9.0, 8.x, and 7.0 Update 2.
• Replication is supported from Arcserve UDP 9.2 source RPS to UDP 9.1, 9.0, 8.x, and 7.0 Update 2 destination RPS.
• Replication is supported from Arcserve UDP 9.1, 9.0, 8.x, and 7.0 Update 2 source RPS to UDP 9.2 destination RPS.
• Virtual Standby backward compatibility policy:
• VSB Monitor/Proxy version should be similar to the Agent version if the backup destination is a shared folder.
• VSB Monitor/Proxy version should be similar to the RPS version if the backup destination is RPS.

• Instant Virtual Machine backward compatibility policy:
• Instant VM recovery server version should be similar to the Arcserve UDP console version.
