Upgrading Qlik NPrinting
Upgrading from Qlik NPrinting 17.0 onwards
From Qlik NPrinting 17.0, an upgrade option is available for both major releases of the software, and for service releases that automatically upgrade Qlik NPrinting. When upgrading, the procedure preserves all data and makes it compatible with the new version of Qlik NPrinting.
Qlik NPrinting 17.3 has increased the number of supported upgrade paths. It is possible to upgrade to Qlik NPrinting 17.3 from any version of Qlik NPrinting in the 17.2 series. All of the following starting points are supported:
Starting from Qlik NPrinting 17.2.1, the Qlik NPrinting Server upgrade process removes RabbitMQ and replace it with the Qlik NPrinting Messaging Service. It is not possible to keep RabbitMQ installed on the same computer of Qlik NPrinting Server 17.2.1 or newer also if it is used by other services than Qlik NPrinting.
Two different tracks are available for Qlik NPrinting:
- Service release track
- Feature release track
If the installed version of Qlik NPrinting 17 is on the service release track, you must upgrade to each successive service release, for example, from 17.0.1 to 17.0.2 to 17.0.3 etc. However, if the installed version is the final service release before a feature (point) release, you may upgrade to the feature release directly, for example, from 17.0.5 to 17.1. if 17.0.5 is the final service release
You must not upgrade from 17.0.5 to 17.2. The previous feature release 17.1 must be installed before upgrading to 17.2 for example.
Thanks for your reply.
There is no clearly mention to upgrade from V17.0 to V17.1.
As per your suggestion in your reply, there is the only possible option is from 17.2 to 17.3 version.
So I thing have to remove 17.0 version and then install 17.3.
Please clarify me if I am wrong.
Which exactly version you have currently installed? 17.0.0
What version you are planning to install?
Are you planning to keep repository or you want to do new vanilla install?
If the installed version of Qlik NPrinting 17 is on the service release track, you must upgrade to each successive service release, for example, from 17.0.1 to 17.0.2 to 17.0.3 etc.
However, if the installed version is the final service release before a feature (point) release, you may upgrade to the feature release directly, for example, from 17.0.5 to 17.1. if 17.0.5 is the final service release
If there is nothing you want to preserve from 17.0.1 then there is no hassle to uninstall old version and do everything from beginning. I would even suggest it.
On the other hand if there are reports, templates or anything in repository you want to keep then in my opinion you would have to do successive upgrades step-by-step.
