There is a document on the support site with Target Code versions which are the recommended revisions https://support.emc.com/docu39695_Target-Revisions-and-Adoption-Rates.pdf?language=en_US

I actually need to rephrase my question. 

I would like to apply all recommended hot fixes for the version of Avamar that I am running. How do I find the recommended hot fixes for the version of Avamar I am running?  (Avamar 7.4)

Thanks for your help!

The following KB is a condensed version of the "Top Level Assembly" (TLA) document that the Dell EMC Remote Proactive team uses to determine what hotfixes should be applied during upgrades:

https://support.emc.com/kb/528409

This KB is updated periodically as new fixes are released.

Note that the fixes in the TLA are not always the most recent fixes. Sometimes a hotfix is deployed as part of a "controlled rollout" to a subset of customers before being added to the TLA. There may also be hotfixes that are never added to the TLA because they are environment-specific and only applied as needed.

I hope this helps.
