This page explains how to uninstall your current version of Java and then install an older version.Users of Banner, App Worx job scheduling, and the Document Imaging indexing module (Singularity) may need to revert to an older version of Java if they've installed a new version that's incompatible with those services. To prevent your computer from automatically updating to the latest version of Java, see Disabling Java Automatic Updates.There are some very special requirements which I have described in this blog As this blog showed here, old Design Studio 1.6.x applications will continue to work even though the server has been updated.However any applications using the legacy HANA JDBC connections need adaptations, and their bookmarks will become invalid. Old Design Studio 1.6 applications that use the ‘Info Chart‘ component do run a little slower when running in compatibility mode. There is one other very small gotcha to watch out for though.Lumira and Design Studio have converged into a single product and a single document type.Whilst there two client-side end user interfaces, one for the Designers (SAP Lumira, Designer) and one for Discovering (SAP Lumira, Discovery) there is a single server Add-on.We strongly recommend you just update without uninstalling any previous Add-on.
However, I also strongly recommend you install all the BI Platform services everywhere too.It will be processed by the new Lumira Server Service.We are not recommending to uninstall the old ‘Design Studio 1.x’ Add-on or uninstalling the old ‘Lumira 1.x’ Add-on.There are sometimes software defects because not all components are installed and doing this before installing Lumira 2 will help avoid those kind of issues.This is especially true when Lumira 1 was run on a ‘dedicated’ machine.Instead a new Lumira Server Service will do all the work of what the old ‘Analysis Applications’ service did.
