Pega Upgrade from 8.7.5 to 24.1.x
Hi Everyone,
We are planning to upgrade Pega platform from version 8.7.5 to 24.1.4 with Classic Websphere Application Server version 9.0.5 running on Java 8. We are planning this upgrade without any infrastructure change (i.e staying with same WAS version on Java 8).
Platform support guide mentions WAS 9.x is deprecated but still can be used with 24.x versions but a support article i came across mentions Pega will not work with Java 8 which in turn needs changes of Websphere server from Classic to Liberty or migrating to Tomcat 9.x version.
This is the link to support discussion - https://support.pega.com/question/pega-upgrade-883-241?
If anybody has recently done this upgrade or came across this issue. Your inputs will be of help.
