HIMSA encourages all locations to upgrade to the latest Noah 4 version, but in some cases, you may need to go back to an earlier version. Maybe one workstation in a large network was updated in error, or a location wants to use a Noah compatible business system that is based on an earlier version of Noah.
- If the machine that was updated and needs to go back is a client in a Noah network, you can just uninstall and reinstall the version of Noah to match the rest of the network.
- If you need to go back to an earlier version of Noah on a server, or a Noah standalone, you will need to take a few extra steps.
HIMSA advises that the Noah database version should match the Noah application version. It is not recommend to downgrade Noah and leave an upgraded version of the database in place, this may cause data issues on future upgrades. For example, if you upgraded to Noah 4.12, you now have a Noah 4.12 database. If you need to go back to Noah 4.9 for example, you should also go back to a 4.9 version of the database.
Before you uninstall:
- locate the latest Noah database Backup that was created with the version of Noah you are reverting to. This backup will need to be restored once you have uninstalled Noah and reinstalled the desired older version.
- If you have added or updated any patient records in the updated Noah version, export those patients from Noah. You can used Advanced search in Noah to only export the records in a specific time period.
