Update qlik sense september 2018 patch 2 to jun 2020

[egodinho]

Good night,
I need to upgrade the qlik sense server from the current version (September 2018 patch 2) to the June 2020 version.
I ask if anyone is aware of any problems in switching from one version to another, or, if it is better to update all major versions, one by one?

Greetings,
Élio Godinho

Hello, 

I know this is an old topic but hopefully it will help!

You do not need to upgrade to each major version between September 2018 and June 2020.

However there is a vulnerability issue addressed between these releases which will require manual operation.
