“Synology DSM and SRM: Access Restrictions for Older Versions May 31, 2023”

That is not correct, in the email I received they advise to save the old old version somewhere in case you need it.

VAs of May 31, 2023, Synology will no longer allow access to installation files for certain older versions of DiskStation Manager (DSM), packages, firmware, clients, and Synology Router Manager (SRM) due to changes in license agreements.

This change may affect owners of older Synology systems and legacy Synology systems (with End of Life or EOL status).

These include:

devices that have not yet been set up,
devices that need to be reinstalled,
devices that need to be updated to the latest software.

Note: This does not affect devices that are still in use.

The software versions below will be pulled from our website and distribution starting May 31, 2023.

It concerns the following products
NAS/SAN (DSM) 6.2.3 a layer
DSM UC 3.1.1-23036 a stock
Video Station 3.0.2 a stock
Audio Station 7.0.0 a stock

Recommendations

We recommend that you upgrade your device(s) to the latest DSM and package versions.

For devices that cannot be upgraded to DSM 6.2, we recommend keeping a copy of your device’s installation files and packages in case reinstallation is required in the future. Go to the download center
