Noah System 4.15.0 (build 6206) will be available for download on our website as of Monday, June 5th 2023.

In Noah System 4.15, the Microsoft CE Database is replaced by SQLite. Support for the SQL CE database has been discontinued by Microsoft. Due to this major upgrade, a number of additional installation guidelines apply. Please follow the following step-by-step procedure to upgrade to Noah System 4.15 on your PC.


To upgrade to Noah System 4.15, the computer will need to be running Noah System 4.14. If you are running an earlier version the update will not proceed. If the installation is not yet on Noah 4.14 please see Upgrade Path for Unsupported Noah System Versions – HIMSA.

Migrating the Noah Database

As part of the Noah System 4.15 installation, the Microsoft SQL CE database will automatically be replaced with the new Microsoft SQLite database.

IMPORTANT: Please note that the migration can take multiple hours depending on your setup. Please see details below.

Before the database is migrated from CE to SQLite, a database backup will be made and the DB Maintenance tool will run on the database. The upgrade will create a separate backup folder and move the old Microsoft CE database backups to  C:\ProgramData\HIMSA\Noah\Backup\DatabaseCEBackup for locations that use the default backup location.

The DB Maintenance tool will run and display the progress made. This may take some time to complete. For an example, a 2GB database may take 20 minutes to backup and to run the DB Maintenance tool.

After the DB Maintenance tool has run, the migration to SQLite will begin, progress will be displayed.

Expected Migration Time: HIMSA’s testing indicates that a mid-range machine should expect 30 minutes per gigabyte in the database. As an example, a 2GB database would take an hour to migrate, whereas a 4GB database would take 2 hours. Outdated or machines of less capability should expect about 1 hour per gigabyte, respectively 2 hours for a 2GB database, or 4 hours for a 4GB database. HIMSA advises you start the migration when there is more time available than anticipated.

Other database changes include:

  • The Noah Configuration database, NOAHCfgDatabase.sdf, will no longer be stored as a separate database file but rather an xml file
  • The Activity log and the WSI databases are also moved to SQLite
  • The new SQLite database has a 4GB size limit
  • The SQLite Noah database file is located at C:\Program Files (x86)\Common Files\HIMSA Shared and called NOAHDatabaseCoreSQLite.db

Logging in to Noah 4.15

The upgrade to Noah 4.15 will continue after the data migration is complete and the Noah login will be presented.

  • If this is an upgrade of Noah, the same user log in settings will be maintained.
  • If this is a new installation of Noah 4.15, the user will be asked to enter a password for the default user ABC. Password is 123.  Requiring passwords is enabled by default in Noah 4.15. If the user just clicks OK on the log in, they will be presented with ‘Invalid login. Please try again.’

Issues during migration

Patient Data

Q: What happens if my patient data fails to migrate?

A: If your patient database is not migrated the installation will be cancelled, and Noah will not be upgraded. Your Noah will continue to function, and we advise that you attempt the installation process again. If it continues to fail, please contact your Noah support engineer for additional assistance.

Activity Log

Q: What is the Activity Log?

A: The Activity Log contains records of all actions performed within Noah. You can read more details about its contents here: The Noah Activity Log

Q: If there is an issue migrating the Activity log, an option will be offered to ignore migrating the Activity log. What happens if I elect to ignore migrating it?

A: If the Activity Log is not migrated, Noah will generate a new and empty Activity Log. Your old Activity Log will not be deleted, but it will not be migrated to the new SQLite database.
