🗒️
INFORMATION: In case there is a need for any PAT file for any model (including critical updates) from version 6.2.x - 7.0 onwards, feel free to post in the comment sections and the link will be posted.

In case you have missed the official news on the Synology site, or their email newsletter, as of May 1st 2023, certain legacy DSM, as well as Surveillance Station, SRM, and some other smaller packages will no longer be supported and as such their installations will no longer be available on the download support site.

What Does That Mean?

  • DSM 6.2.3 and older will be removed from official download servers
  • You need to do download them now as you will not be able to download them later on

Why?

  • There are some/one (AAC)  license in DSM6.2.3 and below which we are not allowed to use/offer anymore
  • Therefore Synology is no longer allowed to offer those DSM Versions.

Is this critical? How many useers are affected?

  • Actually no. DSM 6.2.4 will be still available.
  • DSM 6.2.4 is available on 11-series and up. 10-series support stopped with DSM 5.2
  • Only users with models from 2009 (13 years old) can not download DSM5.X or older

Full info is accessible on the following link as well as below.


Due to changes in our licensing agreements, Synology will from 1 May 2023 remove certain DSM installation files, firmware versions, and software packages from our official website and from distribution. This change may impact owners of Synology systems that have reached end-of-life (EOL) status, as those devices will no longer be eligible for upgrades.

Please note that the following Synology software will not be available from 1 May 2023:

NAS/SAN (DSM) Video Station Audio Station Media Server Surveillance Networking (SRM)
6.2.3 and below 3.0.2 and below 7.0.0. and below 1.4 and below 8.2.8 and below Version 1.1 - 1.1.7 and 1.2 - 1.2.5

💡
Files required to (re-)install old software and firmware will remain available from Synology Download Center until 30 April 2023.

NAS/SAN (DSM)

DSM 6.2.3 will be removed from the website/from distribution and will be superseded by DSM 6.2.4 and above.

💡
For admins of devices that can be upgraded to DSM 6.2.4, but are currently using DSM 5.0 or below, we recommend scheduling an upgrade before 30 April 2023 and archiving the files required to upgrade to DSM 6.2.4.

  • Step 2: Upgrade to DSM 6.0.3-8754 (5/2017)
  • Step 3: Upgrade to DSM 6.2.4

It is clear that Synology is cleaning house of their legacy devices and platforms, so be sure to patch up if possible, or download the installations for archive purposes! This is not a big surprise, as life cycle management happens on HW level just as well as it does on software. By deprecating old models, it is expected that complementary software follows as well.
