We're planning on upgrading DX NetOps Performance Management in the next few weeks and were looking for any "gotcha's" or tips regarding upgrading to or using the current versions.
Current as of 21.2.8
Backup instructions for all components:
Before starting an upgrade for any system component, run the "rpm -qa <packageName>" command for each required package. If it's installed, great, move on to the next one.
If ANY are found missing ensure they're installed.
The libaio is an important required MySql package. Ensure it’s installed to avoid the following issue with MySql start failure post upgrade. Discussed further in the following KB article: https://knowledge.broadcom.com/external/article/142976
See the section on dr_validate.sh

When doing so it’s critical to re-use the DCM_ID the install is assigned so that the devices that DC manages are properly tied back to the ‘new’ reinstalled DC. In case that’s necessary the simple thing to do is gather a set of the DCM_ID values and setting them aside prior to the start of the upgrade.

Ensure the dradmin or equivalent OS users password is valid. If it’s expired or locked out the dr_validate.sh script will fail when it prompts for that users password. Reference article for customers with further details/impacts re: dradmin user password changes.
13. Upgrading VNA gotchas:
Make sure you know the current WildFly admin/WildFly JMS/MySQL root user password before upgrading
Do NOT shut down wildfly/mysql before upgrading.
14. When upgrading a Fault Tolerant Data Aggregator environment, you must upgrade the Data Aggregator proxy BEFORE either of the Fault Tolerant Data Aggregators as in the order outlined in the documentation:
15. If you are upgrading to DX Netops Performance Management 20.2.9 or DX Netops Performance Management 20.2.10, if you have any SNMPv3 profiles with no authentication, this can cause SNMP profiles to fail to load, see:
