If I run a BlueDragon installer and I already have an older version of BlueDragon installed, will I be upgraded without having to uninstall my current BlueDragon?
That depends on whether you are running BlueDragon .NET or BlueDragon JX. BlueDragon .NET will upgrade without having to uninstall. BlueDragon JX requires that you uninstall your current version before upgrading. Your current configuration setting will be saved in \BlueDragon_Server_JX\bluedragon.xml.save.
