Dear Experts,
I'm planning to have a CVP Upgrade from 9 .0 to 10.5 for one of our customers.
I already did the upgrade in my lab and I'm planning the below for the customer:
- Upgrade CVP Reporting server and Operations Console during working hours as they don't affect the Call Flow.
- Upgrade both CallVXMLA and CallVXMLB in a maintenance window.
My concern is the RollBack Plan in case something didn't go as expected.
Has someone faced such an issue?
Thanks is advance.
