Set up automatic deletion of obsolete or expired assessment records.

## Before you begin

Role required: admin

## About this task

Configure the age of obsolete or expired assessments to be cleaned.  
* Obsolete assessments: Invalid assessments, which have been ignored or the associated vulnerable items (VITs) that are closed for more than two years.
* Expired assessments: If you update the firmware version of a device, the existing assessments based on the previous firmware version become invalid and are considered as expired assessments. You can delete expired assessments, which are older than a month. However, you must perform new vulnerability assessments for the devices with an updated firmware version.
