+When you change ruleset versions, it is important to be aware that all of your previous customizations to the managed rulesets will be reset. These customizations include disabling specific rules, adjusting rule actions and applying exclusions.

You can keep this template if you ever need to revert to a previous configuration. You can also clone this template, update the ruleset type, ruleset version, and rule group name to match the ruleset your changing to, then deploy this updated template in your test environment to change rulesets while still preserving your customizations.
