Upgrading Qlik Sense Enterprise Windows from 2020 version to latest

[DOD]

Hi,

We are looking to upgrade our current version of Qlik Sense enterprise (June 2020) to the latest version (November 2023).

Given the gap in versions, can anyone provide guidance on whether an upgrade to an intermediary version is required initially and if so, which version is recommended?

Thank you very much.

Hi @DOD Please refer to "Considerations about older versions" section in the documentation below to know the major changes in versions of Qlik Sense and plan accordingly.

@DOD From my personal opinion, Please go with Feb 2023 (Since then the postgre DB is changed), and then plan anything after.

Hi Chetan,

Thanks for the reference documentation. My understanding from this is what we should upgrade to November 2020 initially.

It appears we can then upgrade directly from that version to November 2023, with the additional considerations regarding the upgrade to PostgreSQL 14.8 to be applied.

Thanks,

Dod

Thanks for the advice, @Anil_Babu_Samineni.

Would this then be an upgrade from Jun 2020 to Nov 2020 (due to .NET framework 4.8) and then an upgrade to Feb 2023 (due to PostgreSQL)?

@DOD What I do this case, 

1) you can upgrade .Net framework directly in Jun 2020

2) Then do the same for postgre SQL

3) Then I will suggest Qlik component (Feb 2023)

@Anil_Babu_Samineni, when upgrading PostgreSQL to 14.8 in the Jun 2020 environment initially, it appears that this cannot be done using the QPI (Qlik PostgreSQL Installer), due to the older QS version.

I see the following comment in the QPI documentation: 

• Upgrade an existing bundled database from PostgreSQL 9.6 and 12.5 to 14.8. The QPI only supports Qlik Sense Enterprise on Windows February 2022 and above. It's recommended that you upgrade to the latest supported version of Qlik Sense before using the QPI.

Does this mean, that PostgreSQL should be upgraded manually in the Jun 2020 environment?

@DOD I have followed this article, Upgrading and unbundling the Qlik Sense Repository... - Qlik Community - 1934238

In this case from your site, It may not possible until you go to one of the version where Postgre SQL works. I am rephraming my sequence order.

1) you can upgrade .Net framework directly in Jun 2020

2) Then I will suggest Qlik component (February 2022)

3) Then do the same for postgre SQL upgrade

4) Then I will suggest Qlik component (Nov 2023) -- this works because you have both DB and dot net that is supportive.

I would better you to suggest to go latest version of postgre SQL (At least 14.x), you can read more here: PostgreSQL | endoflife.date

Because, all the above steps performed and tested fine. I will suggest you to go with pre production to see the bugs.
