What is required before upgrading Deep Security Agents (DSA) to DS 12?

Upgrading Deep Security Agents (DSA) is a critical step in maintaining the security framework of your environment, and it requires certain prerequisites to ensure that the transition is smooth and effective. Upgrading Deep Security Relays first is vital because these relays act as intermediaries between the Deep Security Manager and the Agents.

By upgrading the Relays ahead of the Agents, you ensure that they are fully capable of communicating with the newer version of the Agents. Relays provide the necessary updates and information to the Agents, and if the Agents are upgraded before the Relays, they may not find the appropriate communication pathways, which can result in deployment failures or configurations that are not compatible with the new agent version.

Ensuring that the infrastructure is in the correct order, with Relays upgraded beforehand, helps facilitate a more efficient upgrade process for the Deep Security Agents and supports the integrity of the security management system overall. This structured approach minimizes downtime and potential inconsistencies within the security policies being applied across the network.
