NetApp 8.3.1P2 is considered supported and any issues found will be fully investigated.
Change Auditor 6.7.1519+ was tested and is fully supported with NetApp 8.3.1. We perform full regression against minor releases only (for example, 8.3.0, 8.3.1, 8.3.2). Interim patch releases are not subject to full regression testing. We encourage customers to conduct their own testing as they see fit, as different environments/configurations may impact the outcome.
We will continue to test all major and minor version updates from NetApp going forward but do not plan on testing the patches.
