I am upgrading to 15.4 from 15.3. I want to make sure that the configuration and filters that have been developed are not impacted by the upgrade. Will these be impacted?
Ideally none of the filters and custom views should be impacted with an upgrade.
But having said that, I have seen custom user views being defaulted back to system view after the PMO was upgraded. Hence request you to thoroughly check this in a lower environment before upgrading prod.
