    When it comes to new feature settings in TCP and HTTP profiles, I would say your chances of facing a negative impact are quite low, unless you defer from the defaults. But why not go over the documentation to see what each of the options do?

     

    General rule is that there's no such thing as 100% retention on functionality when doing major upgrades. New features and occasional default-profile over-rides are pushed into TMOS whether you want them or not. Thousands of 'insignificant settings' will change without your consent. Therefore, always assume some negative impact, unless you have done the exact same upgrade for an appliance running the exact same configuration elsewhere.

It makes sense. As the first step, focus on the appliance upgrade (or migration) intervention, where the main goal is to retain as much of the existing functionality as possible. After a week of successful operation, I normally proceed with second step to implement the new features I find interesting. With this way of working you can set a better scope on troubleshooting efforts, should there be any issues.
