DSM 6.2 has helped companies worldwide manage their workloads with its high stability and efficiency. The proven reliability has led DSM 6.2 to a Long-Term Support (LTS) version maintained until 2024. For more information about DSM life-cycle phases, please refer to the Synology White Paper.
Update your DSM smartly
Your Synology NAS will automatically notify you of required DSM updates based on your system settings, saving you the hassle of evaluating whether a new DSM version should be installed on your Synology NAS.
Towards smoother and faster migration
Migration Assistant allows you to migrate data, packages, and system configurations from one server to another, while keeping all the services on the original server available and syncing any changes to the target server in real time. Unnecessary reboots can therefore be avoided to maximize service uptime during migration.
