Your device model and current system version meet the upgrade requirements, and you can upgrade to TOS 6.0.530.
This upgrade will not erase the data stored on your hard drives. However, since this is a major-version upgrade from TOS 5 to TOS 6, some system configurations, such as usernames and user permissions, may be reset or removed during the upgrade. You may need to reconfigure these settings after the upgrade is complete.
To avoid any unexpected issues, we recommend backing up your important data before upgrading and recording your current user accounts and permission settings so that you can restore them afterward.
