SFOS 18.5.2 MR-2 to 19.5 upgrade path

Hi pgri

I would suggest to upgrade SFOS 19.0.2 MR2-Build472 monitor it for sometime then upgrade to SFOS 19.5.0 GA-Build197, refer to the below kba for more information :

Thanks and Regards

Hi,

Thank you for reaching to Sophos Community.

In addition to Bharat suggestion, kindly see the following guide

docs.sophos.com/.../index.html

Even more confused now.

The first reply indicated going to 19.0 MR2 - but in the table above that is not a upgrade path to 19.5 GA

18.5 MR5 isn't a direct upgrade either.

What does 18.5 GA to MR4 mean ?

Hi pgri  The "Upgrade From" column indicting source firmware I.e. current firmware in which your XG device is running.

18.5 GA to MR4 mean ==> 18.5 GA, 18.5.1 MR-1, 18.5.2 MR-2, 18.5.3 MR-3, 18.5.4 MR4

Okay, thank you.

 I can confirm that we successfuly upgraded from 18.5.2 MR2 to 19.5.0 GA-Build197 two days ago.  The upgrade of the HA pair completed without any issues.

Hi pgri  Thanks for sharing the latest feedback here.
