I made a post about this on our forums (first post on the forums actually haha) but decided I needed to make a front page post. Please save yourselves the heart ache and grief and just read the damn release notes before you upgrade firmware versions. Technician friend of mine apparently doesn’t like reading too much. Either way, he took a firewall straight to 5,4,1 from an unsupported firmware upgrade path. Yeah, I know, 5.4.1, too early for production, I get that….but the issues he is experiencing are due to his lack of release note reading.
So PLEASE save yourself the trouble and pain and just read and follow the release notes!
