You need a quick way to transfer iManager user preferences to a different iManager installation.
The iManager user preferences are stored locally on each iManager installation. Each user who ever logged in on that iManager installation will get a directory with his preferences stored in various files. These directories can be found in tomcat\x\webapps\nps\WEB-INF\config (where x is the version number of the tomcat use for the iManager installation). It is enough to copy the preferences directory for a user with all the files contained in it to the same directory structure on the destination installation and the same preferences will apply there.
Note that you should only do this if you are using the same iManager version for both installations. Between different versions of iManager, the preferences are not guaranteed to be the same.
