Troubleshooting Cisco Elastic Services Controller Upgrades
Problem Statement:
How can I choose ESC upgrade approach?
Description:
There are three upgrade approaches for ESC Upgrade and following are the criteria for your reference to choose the best approach for upgrading your ESC setup.
Solution:
-
If your upgrade path is between ESC patch builds, for example, from ESC 3.1.0.116 to ESC 3.1.0.145, consider RPM upgrade as your first choice.
-
If your upgrade path is between ESC official FCS release, for example, from ESC 3.0.0 to ESC 3.1.0, RPM upgrade will not work in your situation and you can only do the image upgrade.
-
For a healthy ESC HA, consider in-service upgrade.
-
For Standalone ESC or ESC HA with only Master VM, take the database backup/restore approach.
