DSM 6 vs 7

DSM 6 vs 7

Version: 7.0-41882 Release Candidate

Important note

Before Update

1. Before updating, your Synology NAS should be running DSM 6.2 or above versions.
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. If you’re performing a clean installation, make sure to complete the installation with find.synology.com or Synology Assistant 7.0-50029 or above.
4. To avoid possible compatibility issues, users who installed Active Insight, Synology Photos, and Secure SignIn mobile applications during DSM 7.0 Preview/Beta programs should update the applications to the latest version after the DSM update.
5. DSM 7.0 consumes more system resources, including memory. If your model has less than 1 GB of memory, updating to DSM 7.0 may affect system performance.
6. For the models below, you can only download the upgrade patch from Synology Download Center because you won’t receive notifications for this update on your DSM.
   • 15-Series: RS815RP+, RS815+, RS815, DS2415+, DS1815+, DS1515+, DS1515, DS715, DS415+, DS415play, DS215+, DS215j, DS115, DS115j

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. DSM 7.0 will end support for ext3. We strongly suggest backing up the data stored on your ext3 volumes and transferring the data to volumes with supported file systems before the update.
3. DSM 7.0 by default disables NTLMv1 and enables NTMLv2 only, so SMB clients (e.g., Windows XP devices, media players, network printers, smart TVs, and IP cameras) won’t be able to access your Synology NAS. To restore the connection after the update, go to Control Panel > File Services > SMB > Advanced Settings > Others and enable NTLMv1 authentication.
4. Creating SSD caches on block-level LUNs is no longer supported. Existing SSD caches for block LUNs will function normally after the update.
5. NT4 domains are no longer supported. Current NT4 domains will be unavailable after the update.
6. The URLs used by DSM when updating or running services have been modified. Please read this article and make sure that your firewall rules are configured appropriately.
7. iSCSI Manager will become SAN Manager on DSM 7.0. Please refer to package release notes for more details.
8. 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.
9. EZ-Internet is merged with Router Configuration in Control Panel. To set up port forwarding, go to Control Panel > External Access > Router Configuration.
10. 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.
