Upgrade could be complex task, depending on changes in configuration files of basic dcm4chee installation.

Upgrade Procedure:

1. Shutdown dcm4chee
2. Extract the new version to a different folder dcm4chee-xxx-2.yy.y
3. Copy files from JBoss to dcm4chee (see points 2. and 3. of Instalation Instructions)
4. If you have installed Audit Record Repository, then install it (see point 5. of Instalation Instructions)
5. Execute every upgrade script in the dcm4chee-xxx-2.yy.y/sql directory higher then your current version (means if you have 2.11.x execute update-2.12.xxsql and update-2.13.xxsql upgrade script)
6. Copy all following directories/files from old to new installation directory:
   • dcm4chee-xxx-2.xx.x/server/default/archive (if there are your DICOM archive files)
   • dcm4chee-xxx-2.xx.x/server/default/data/xmbean-attrs (there are MBean settings)
   • dcm4chee-xxx-2.xx.x/server/default/deploy/pacs-*-ds.xml (if you have older version, its name may be *-ds.xml - then rename it)
   • if you have installed Audit Record Repository, then copy dcm4chee-xxx-2.xx.x/server/default/deploy/arr-xxx-ds.xml
   • if you replaced JAI Image IO files in dcm4chee-xxx-2.xx.x/bin/native then copy them
   • if you changed or added any other files manually, then you should merge them to their new dcm4chee versions (it may be complex task), i.e. run.bat, run.conf (changing heap memory), JavaService.exe, dcm4chee-xxx-2.xx.x/server/default/conf/*
7. Start dcm4chee
