This section will describe how you can upgrade Intrexx, meaning change the Intrexx version.
In particular, it will look at upgrading from 18.03 to 19.03.
You need to make key changes to the Intrexx configuration when performing this upgrade.
This particularly relates to the "embedded Tomcat" that is an integral part of Intrexx
from Version 19.03 onwards.
There are two different approaches to this upgrade.
Upgrade an existing installation
You can install Intrexx 19.03 in a directory where a previous version has already been installed.
A key advantage of this approach is that all existing configurations from the previous
Intrexx version are kept.
You can install Intrexx 19.03 in a new directory. This approach starts just like a
new installation. After the installation, you need to transfer data from the
previous version to Intrexx 19.03.
