Different BRMS versions in one git repository cluster
Issue
- We're planning an upgrade to our system from BRMS 6.1.3 to BRMS 6.4.0. The environment consists of 5 servers clustered with BRMS git repository cluster managed by Zookeeper and Helix. As we want to avoid entire downtime, I plan --- 1) Split the domain into 2 domains. 2) Upgrade the version one-by-one without shutting down both domains. Is it safe?
Environment
- Red Hat JBoss BRMS
- 6.1.3
- 6.4.0
