I've been running my unraid server for a couple years. I'm on version 3.0 Pro. asically it has worked fine and haven't paid any attention to the website. Well now I see you guys are up to ver 4.4 . What do I need to do to upgrade from 3.0? What features will I pick up. I've been trying to read through some of the release notes but I'm so far behind it's hard to tell.

Upgrading is very easy for the newer releases.  You only have to replace 2 files.  But to upgrade from 3.0 is a bit more involved.

 

Here are the instructions from Tom's announcement thread (here).

 

If you are currently running unRAID Server 3.0-beta1 or higher, please follow these steps to upgrade:

 

1. Referring to the System Management Utility 'Main' page, make a note of each disks's model/serial number; you will need this information later.

 

2. Shut down your server, remove the Flash and plug it into your PC.

 

3. Right-click your Flash device listed under My Computer and select Properties.  Make sure the volume label is set to "UNRAID" (without the quotes) and click OK.  You do NOT need to format the Flash.

 

4. Copy the files from the new release to the root of your Flash device.

 

5. Right-click your Flash device listed under My Computer and select Eject.  Remove the Flash, install in your server and power-up.

 

6. After your server has booted up, the System Management Utility 'Main' page will probably show no devices; this is OK, navigate to the 'Devices' page. Using the model/serial number information gathered in step 1, assign each of your hard drives to the correct disk slot.

 

7. Go back to the 'Main' page and your devices should appear correctly.  You may now Start the array.

 

Just for future reference, there is now a FAQ entry for this, How do I upgrade the unRAID software?.  And it links to a special wiki page, Upgrading from version 3.

 

By the way, the easiest way to review the release changes is by reviewing the Release Notes wiki page.
