DSM 6.2 Upgrade (From DSM 6.1)

Synology News

DiskStation Manager 6.2 (DSM 6.2) has been out for a couple of weeks, and you may be considering the upgrade. Here’s the overall process to follow and what to expect.

Prep Work

There are a few things to do before you begin the upgrade.


Update DiskStation Manager to the latest version of DSM 6.1. Also, update all installed packages to their most recent version. While this isn’t an absolute requirement, it’s the safest way to upgrade.

I also like to reboot the NAS before the upgrade. The reboot gives me extra confidence that there’s no problem hiding in the old software. I admit to skipping this if there’s been a reboot in the last few days.


Make sure you have backups and that you can restore the data from them. If you use Hyper Backup, you can verify the backup integrity. Select the backup task, then click the drop-down hamburger menu and select Check backup integrity.

If the backup is encrypted, you’ll be prompted for the encryption password. Then you’ll be prompted to select the type of check to do. You’ll want to confirm that the data can be restored, so check that box. The integrity check will take a long time, and depends on the amount of data that you have.

The Integrity Check will the begin.

Wait for it to finish.

Obsolete Features or Packages?

Make sure you aren’t using any features or packages that can’t be used on DSM 6.2. There are only a few things that lose support with DSM 6.2. These include:

  • The WiFi dongle won’t support parental controls or the device list if set in bridge mode.
  • Virtual Machine Manager will no longer support creating clusters on older DSM versions.
  • SSH authentication by DSA public key is prohibited for security reasons.
  • Office 2.x and below are not compatible with DSM 6.2.

The full release notes are here.

The Upgrade

Even though the update settings are set to “Newest DSM and all updates” the new DSM 6.2 version will not be made available (at least not at this time).

To do the upgrade go to the Update & Restore section of Control Panel.

The top of the DSM Update panel will have a link to the Synology website.

Click the link to go to the download section of the Synology website. It will automatically find the downloads for your Synology NAS. Click the Download (pat) link to download your firmware. Remember the download destination.

Once the firmware file download is complete, return to DSM Update in control panel and click the Manual DSM Update button.

Use the open file dialog to select the file that you just downloaded.

When you click OK, you’ll receive a confirmation prompt. When you click Yes to this prompt, the upgrade will start.

The 10 to 20-minute estimate is generic, and not based on how long your own NAS will take. My DS1815+ took less than 5 minutes to do the upgrade.

Once the upgrade is done, and the NAS reboots, the login screen will be displayed. Go ahead and log in. You’ll have to confirm (or deny) some privacy settings.

You should also check notifications to see if anything else needs to be done. In my case, I had two related notifications. I needed to update a couple packages and setup bad sector warnings. Click the link in the message to go to the correct location to make the change.

Clicking on the Package Center links opens it up. In my case, I had to update Virtual Machine Manager and Storage Analyzer. Click the Update All button to save time.

Clicking on the disk warning setup link opens Storage Manager and automatically goes to the HDD/SSD General section. Make the changes you feel are appropriate. My choices are shown below.

The upgrade is complete, and everything is ready to use.
