Synology has released the latest and greatest version of DSM 7 on June 2021 but I just upgraded today. If it ain’t broke, don’t fix it. However, the Christmas holiday give me some room in case the upgrade didn’t go well. Luckily, there is no major issues.
I used the following applications before the upgrade:
- Photo Station
- Docker — I have my Unifi controller and Folding@home running in containers
- CardDav Server
- Video Station
The upgrade was from DSM 6.x to DSM 7.1.1-42962 Update 3. It is running on DS218+.
Applications That Don’t Work Anymore
Photo Station and CardDav server.
Synology introduced Synology Photos to replace Photo Station. The photos are still there but I needed to install the Synology Photos Mobile on my phone and setting up the automatic backup again. All the photos and videos are still there.
CardDav, however, is a different story. It is replaced by Synology Contacts but all the contacts that I had before were all deleted. Since I am not using CardDav as my main contacts, I have no issues with it. But if you do use carddav heavily, please consider to do the backup before doing the upgrade.
I do remember vividly that they told you about this possibility when I started the upgrade process but I completely ignored it since I am not using CardDav that much.
Applications That Work
There were no issues whatsoever with Docker and the Video Station. They just keep working as expected. All containers are running immediately after the upgrade without problems.
