Unfortunately, as this is an enterprise product, I can't share those files. If there is specific information you are looking for from them, I may be able to provide an excerpt with pertinent information redacted/removed. To the other questions, Migrating to lo4j2 version 2.20.0 Open JDK 17.0.14 OS: Amazon Linux version 2023, ID like Fedora 2023
W/r/t the log4j configuration, it appears we're using multiple log4j.xml files, some of which are log4j2 and otheru sing log4j, so I don't think they have been converted. Is there a page I can reference with instructions on how to convert those files?
