Upgrading XG115 from SFOS 18.0.6 MR-6 to SFOS 18.5.1 MR-1: Backup restore not working?

Question

Hey everybody, 
 I'm trying to upgrade a XG115 appliance from SFOS 18.0.6 to SFOS 18.5.1. 
 I've created a backup of the config from within the 18.0.6 firmware and downloaded and installed the 18.5.1 release . 
 All settings were reset to factory defaults, which was to be expected. 
 However, I'm unable to restore the 18.0.6 backup. 
 The process simply errors out, complaining that the backup can not be applied to this firmware version. 
 Can someone give me a hint how exactly one is supposed to upgrade the firmware without losing the configuration? 
 Thanks in advance, 
 Dominik

Yes - Its the wrong file. You have the Software Update File. Please go to the mySophos Portal and look for your Appliance under Devices. There is a Download Link to the HW Image.

No. 
 Let me rephrase it: 
 The is and will always be a upgrade path from A to B. 
 Sometimes a release is a "blocked" scenario. Means a release like V18.0 MR6 is released after V18.5 MR1. So V18.5 MR1 does not support the version V18.0 MR6, as it "does not know, MR6 exists in the first place". 
 So to workaround this, Sophos will release the next release (V18.5 MR2), which will be the official supported upgrade path: V18.5 MR2 supports all currently released firmware versions. 
 But V18.5 MR2 is currently not being pushed out to every customers via Up2Date (check new firmware). This will be done in stage phases. But you can download the MR2 via MySophos.

Hi, 
 you go to the GUI -> backup and firmware -> firmware -> in the firmware field you click on the version with the arrow and follow the instructions.
