We have in the past updated our Atoms using the Dell Boomi Script in order to support Java 8. Those scripts on execution have installed JRE8 and updated the needful config file. We are now planning to upgrade our Molecule to support Java 8 using the Dell script. Does this script install JDK? Please also provide me the list of files I need to backup prior to script execution so that I may roll back in case the upgrade fails.
