First use the "update 2.0.4.app", next the "update 2.0.4 to 2.0.5.app", then the "update 2.0.5 to 2.0.6.app", followed by the "update 2.0.6 to 2.0.7.app" and then the "update 2.0.7 to 2.0.8.app" files to update your CaseMgrDATA folder to v.2.0.8. Assuming your data folder is currently at v.2.0.3 or earlier, this is the first step to updating to v.2.0.9. The next step is to use the updaters provided with the 208-209 update to finish up.

To determine which version is currently installed, run De Novo CaseMgr and go to the Help Menu. Choose "About De Novo CaseMgr". Versions 2.0, 2.0.1, 2.0.2 and 2.0.3 will be identified by that number. If you are using v.2.0.4 or later, the window will say something like "v. 2.0.40/2.0.4" or "v.2.0.50/2.0.5". The first number is the version of your local De Novo CaseMgr.exe file, the second, the version of the CaseMgrDATA folder. They should be the SAME version. If you  are not currently using v.2.0.8 of the data folder, use one of the other updaters to update your data folder to v.2.0.8, and then use the 2.0.8-2.0.9 updater to update both the data and program to v.2.0.9

HOW TO UPDATE:
The update .app files are used in succession to update the data folder. If you're already running v.2.0.8, you only need one update .app; the one provided with the 208-209 update.

If your version of CaseMgr 2.0.3 or earlier, you will run several update .app files from the Administration Menu's Update CaseMgr... option. The updater.app files, used to update the CaseMgrDATA folder, may
be run from any copy of De Novo CaseMgr currently linked to the shared CaseMgrDATA folder. The user must be logged into CaseMgr as a Supervisor or Administration-level user so the Administration Menu is accessible. The shared data folder is updated, and all workstations will be sharing the updated data folder. This update process from the Administration Menu is done just once, from any station, but nevertheless, this 203-207.exe updater should be applied on every licensed De Novo CaseMgr workstation. The updater .app files will not be used locally, but this update utility offers updated plugins provided for the plugins folder inside the local De Novo CaseMgr program folder.

To run the updaters, choose "Update CaseMgr..." from the Administration menu and use the "Select Updater" dialog to choose the appropriate updater .app file. They should be used in succession, beginning with the earliest. After selecting the updater, it's necessary to quit CaseMgr before using the next required updater.

Remember, Administration Menu updates needs to be done only one time. There is no need to run the updates from multiple copies of CaseMgr. If you have multiple stations, however, all stations will also need the new De Novo CaseMgr.exe file provided by the 208-209 updater.
