Upgrading from version 2.X to version 3.X
iSymphony 3 is a complete ground up rewrite of the iSymphony system. Because iSymphony 3 utilizes many new technologies and implements features and configuration in a completely new way, there is currently no direct upgrade path from iSymphony 2 to any version of iSymphony 3 or higher. If you are upgrading from iSymphony 2, you will have to deploy iSymphony 3 as a new installation and configure it from scratch. Please see Installing iSymphony for details on how to perform a new installation. iSymphony versions 2 and 3 can be run simultaneously on the same system without issue.
