UPDATE: 27/12/2020 - DSM 7 will NOT be coming to DS1821+ model but it will be supported in the full release

Yesterday was an exciting day for Synology. We have got our first DSM 7 public beta after three months of public preview and over 2,5y since the initial announcement of DSM 7.

I have been running the public preview version since day one and have had no problems at all. The NAS was stable and running fine with no major problems (apart from the volume degradation at one point, but that was just the old drive dying), so today I have updated to DSM 7 41222 version (public beta).

Let's see how that went!

In case you have missed my latest articles on DSM 7 overall have a look here, and if you want to get on board with the latest public beta you can download it here.

NOTE: Understand that this is still a beta. Nothing in DSM 7 is still final and it's subject to change or complete remap in the end. In some cases, some features might be completely removed!

Head to DSM 7 public beta site here: https://prerelease.synology.com/en-global/download/dsm70_beta and download the version for your model.

Here are the highlights for this 41222 version:

Before Update

  1. DSM 7.0 can only be updated from DSM 6.2.
  2. Reserve extra time to complete DSM 7.0 update. The DSM update takes 10 to 20 minutes, while package update may take more than an hour. The actual time depends on the computing power of your model, the number of media indexing files, and the number of packages installed.
  3. The official version of Active Insight, Synology Photos, and Secure SignIn mobile applications are available in app stores. To avoid possible compatibility issues, users who installed these applications during DSM 7.0 Preview program should update them after the DSM update.

DSM

  1. USB devices (Wi-Fi dongle, Bluetooth dongle, 3G/4G dongle, USB DAC/speaker, and DTV dongle) are no longer supported. If your Synology NAS is currently connected via a wireless dongle, it will be disconnected after the update.
  2. Creating SSD caches on block-level LUNs is no longer supported. Existing SSD cache for block LUNs will function normally after the update.
  3. DDSM is incompatible with DSM 7.0. To continue using DDSM, you should retain the current DSM version. To update to DSM 7.0, please delete DDSM first.
  4. To provide comprehensive TLS support and ensure compatibility, the TLS/SSL profile level in Modern compatibility will automatically change to Intermediate Compatibility after the update.
  5. EZ-Internet is merged with Router Configuration in Control Panel. To set up port forwarding, go to Control Panel > External Access > Router Configuration.
  6. Python3 is merged into DSM as a built-in service. The original Python3 package will be unavailable in Package Center and you can remove it manually.
  7. The following DDNS providers are removed from the service provider list at Control Panel > External Access > DDNS:
    CloudNS, DNO-O-Matic, DNSEXIT, Dynamic DO!.jp, Joker.com, RU-CENTER, TwoDNS.de, Variomedia, Zoneedit.com
  8. The updated QuickConnect connection is secured with an SSL certificate, and your QuickConnect domain will be passed to Let's Encrypt for certificate application purpose. Please refer to the Privacy Statement for more details.
  9. Video conversion to FLV and MPEG-4 Part 2 formats on the following models is no longer supported.
  • 20-series: DS120j

  2. Cloud Station Server and Cloud Station ShareSync will be upgraded to and merged with Synology Drive Server. If you are using any Cloud Station Suite applications (Cloud Station Server, Cloud Station Drive, Cloud Station Backup, Cloud Station ShareSync, or DS cloud), you must switch to their counterparts in the Synology Drive Suite to ensure compatibility. See this page for more details.
  3. Central Management System no longer supports managing Synology NAS with DSM version earlier than DSM 6.2. Please update all managed servers to DSM 6.2 or above first. Managed servers that are unable to update to DSM 6.2 should be disjoined from Central Management System before the update.
  4. MariaDB 5 is incompatible with DSM 7.0. To update to DSM 7.0, please install MariaDB 10, migrate the database, and uninstall MariaDB 5 in Package Center first.
  5. If you cannot find certain Synology approved third-party packages in Package Center, check out this article for the latest status of the packages. For other third-party packages, please contact their developers for more information.
  6. The following packages are no longer supported:

  2. In Central Management System, if the CMS host runs DSM 6.2 (or earlier) but the managed servers run DSM 7.0, the CMS host cannot manage package updates for the managed servers.

Installing DSM 7 4122 beta

Like any other manual installation, DSM 7 beta is nothing different. Go to Control Panel > Update & Restore and on the DSM Update tab use the Manual DSM update button.

Start your DSM 7 beta update here

Now just follow the wizard.

Select the file you have downloaded for your NAS model
Bit of information and warnings
Point of no return once you click Yes

Update on my RS3614RPxs model was 12min including installation, reboot, and reconfiguration of all the settings and packages. Of course, that will depend on how many tasks DSM needs to do on your setup and what version you are updating from.

Upgrade process started
Going well so far
Leave your NAS to reboot as the next phase will kick in after that

As soon as your NAS has rebooted it will continue the installation and configuration process by checking your DSM packages.

Update of your DSM packages

Finally, you will be done, and logging into DSM you will notice immediately some facelift changes.

DSM 7 beta up and running!

The What is new in DSM 7.0 wizard will point you to some important new features supported by your NAS.

NOTE: some elements and features will not work on all devices (like Active Insight).
Skip or select features you want to activate (you can do it later as well)
RS3614RPxs running DSM 7 41222 version

That's it! All done. As I said before it took a bit over 10 min for all of it to complete, and with 0 problems on top of it all.

A few screens that show how the new DSM 7 beta looks like (the font and colors have been tweaked a bit from the preview version):

DSM 7 - 41222 Control Panel
DSM 7 - 41222 Application menu
DSM 7 - 41222 Desktop with several windows (Resource monitor, CMS, and Docker)

Be sure to check all the other article from the DSM 7 series for a more in-depth looks into some of new features and apps.

Let me know down in the comments below what you think about the new beta and if you will jump on in or not!
