A setup for Apigee edge (v4.14.07.00) currently is using 5 node cluster. Is it possible to upgrade one server at a time to 4.15.04.01-EL6.6?
What are the steps/sequence to do this?
The procedure for doing a “zero-downtime” upgrade is described int he Edge Installation Guide. It shows how to upgrade Edge one node at a time.
