17.0 to 17.1 update factory default prompt

Question

Trying to update XG115w_XN03_SFOS 17.0.8 MR-8 through web interface using HW-17.1.0_GA.SF300-152.gpg and get the message "The firmware will boot the device with factory default configuration" each time the firmware is uploaded so I have to cancel. It's a remote xg in production deployment and factory defaulting would be unwanted. Is this a known problem?

Hi, 
 
 Good day! 
 
 As per Sophos advise. Please do not upgrade yet from 17.0.8 MR-8 to 17.1 for specific units (XG115 and below) as the firmware has a high memory usage issues. I suggest to revert back to mr-8 and wait for the new firmware version. This is all according to Sophos.

Hi Pal, 
 
 Good day! 
 
 Wireless models are incapable of HA set-up, anyways as per Sophos Philippines advise, XG115 model or below are not recommended to upgrade to 17.1 and its confirmed that we have to wait.

Hi Pal, 
 
 Good day! 
 
 I also ask Sophos Philippines same question because one of our client with XG105 have the same issue. I've got the information last Monday on a Sophos Partner event, so its legit and advisable that from XG115 below its not recommended to upgrade to 17.1. 
 
 Warm Regards,
