In some cases the IVA tasks can get lost after firmware update.
There are 2 ways. In both ways it's not guaranteed that all task shall work afterwards since new firmware version can contain a new IVA version with new features. So please double check afterwards. It shall at-least save some time instead of starting from scratch.
Via the Configuration Manager save your configuration and load it back afterwards
Copy/paste the scripting text from "IVA task editor"
