Architecture:
- Two V10k G3 appliance with web, email and data security enabled. One of appliance is the Policy Broker.
- One off appliance TRITON Manager running on VM Win 2008 R2 which is our Log server and DSS installed as well
**********************************************************************************************************************
Concern: We want to get the minimal downtime as we cannot afford loosing data security incidents nor logs. Please correct if the below approach is incorrect and confirm us the best practice.
- Suppost that all pre requisites are satisfies like hotfix and patches.
Work flow:
1. Failover the email and web traffic to secondary V10k G3 appliance running 7.7.3, ensure the working and stability
2. Upgrade the primary appliance, Policy broker to 7.8.3
3. Break the connection b/w secondary applaince and TRITON running on 7.7.3 (will start lossing the DLP incidents while processing the email & web traffic) (Q. do we really have to break the connection b/w the same)
4. Upgrade TRITON Management to 7.8.3
5. Restore the web and email traffic to Primary appliance (Policy Broker) running 7.8.3 after establishing all the connection b/w primary appliance and TRITON manager
6. Upgrade the secondary appliance to 7.8.3 and rejoin to the current set up.
Please let me know if this will work?
