When performing a ColdFusion 9 multiserver upgrade, the existing ColdFusion 8 server must be uninstalled first. The instructions from Adobe recommend archiving the existing ColdFusion 8 configuration files ($JRUN/servers/*/cfusion?ear/cfusion?war/WEB-INF/lib/neo-*.xml) for migration manually after ColdFusion 9 is running. Place the configuration files in $JRUN/servers/*/cfusion?ear/cfusion?war/WEB-INF/lib/cf8settings and set the flags to start the migration wizard. However, what isn't mentioned anywhere that I noticed is that the migration wizard does not prompt for the new JRun/ColdFusion administrator's password. I'm assuming it's using the administrator password of the files to be imported. Since I didn't know that, I had to turn off security (edit the neo-security.xml file within the instance to receive migrated settings, set admin.security.enabled to false) while performing the migration, and enable it once complete.

The migration worked for many things -- I haven't done an exhaustive comparison yet -- but it did not bring in search collection definitions. Fortunately, I just finished writing an application that read an XML file and populate an instance with the correct datasources, mappings, custom tag paths, search collections, and scheduled tasks. It's based on Sean Corfield's FW/1 because I wanted it to be entirely self contained. The single-file framework was just the ticket. Perhaps my employer will want to release it as open source software. If you have any interest in such an application, please let me know.
