According to a recent notice issued by Synology via email, Synology DSM 6.2 will terminate its service on October 1, 2024. Synology DSM 6.0 was released in early 2016, and Synology DSM 6.2 was released in 2018. It has been five years now, and it will be more than 6 years before it is released on October 1 next year.
For an operating system sub-version, it is not a short period of time to provide support for more than 6 years, so Synology hopes that users can upgrade to the DSM7.x series before terminating the service.
Currently, the latest version of Synology's operating system is DSM7.2. After the termination of service for DSM6.2, Synology will no longer provide any security updates for it. It is necessary for users to upgrade to DSM7.2.
Whether it can be upgraded to a new version is a question. According to Synology's explanation, basically Synology NAS purchased after 2013 supports upgrading to DSM7.
Those that do not support upgrade include:
XS series: RS3412xs, RS3412RPxs, RS3411xs, RS3411RPxs, DS3612xs, DS3611xs
Plus series: RS2212+, RS2212RP+, RS2211+, RS2211RP+, RS812+, RS812RP+, DS2411+, DS1812+ , DS1512+, DS1511+, DS712+, DS412+, DS411+II, DS411+, DS213+, DS212+, DS211+, DS112+
Value series: RS812, RS212, RS411, DS413, DS411, DS213, DS212, DS211, DS112, DS111
J series: DS413j, DS411j, DS411slim, DS213air, DS212j, DS211j, DS112j
Others: NVR216, NVR1218, DDSM
It should be emphasized that although the above-mentioned models will no longer be able to upgrade and receive security updates after October 1, 2024, the NAS itself can continue to be used. However, continuing to use unsupported DSM without security updates will pose security risks.
