Cedric 4.0 or higher requires a database upgrade from SQL Server 2008 to SQL Server 2017. A compatibility check has been added to Cedric v4.0 to make sure the correct version of SQL Server is installed before Cedric can be used.

The first time you start Cedric 4.0 the following dialog will appear:

The steps below will guide you through the upgrade process.
You will need to download two packages with a combined size of around 660MB, so we recommend performing the upgrade when download costs are minimal (for example, while in port and using a Wi-Fi connection):

Step Description
1 If you want to upgrade to Cedric 4.0, start Cedric v3.6 (or lower).
Perform a Check for Updates to download and install Cedric v4.0.
2 Restart Cedric which will cause Cedric v4.0 to start.
The Database Upgrade Required dialog will appear (above).
3 Backup the database using the Backup Database button shown in the screenshot above.
Copy the backup to a safe place.
4 Restart your computer to ensure all database locks are released.
Be sure not to start Cedric after restarting the computer!
5 Login to the computer using an account that can run Cedric.
6 Download and install Service Pack 4 for SQL Server 2008 (instructions below).
7 Download and install SQL Server 2017 Express (instructions below).
8 Restart the computer.
9 Start Cedric.


The steps in this guide perform an ‘in-place’ upgrade of an existing installation of Cedric. Cedric 4.0 is supported on Windows 10 (64bit), and Windows Server 2012 R2 (64bit).
If you are installing a new instance of Cedric v4.0, there is a separate installer available that includes all prerequisites including SQL Server 2017 Express.
Therefore, if you are installing Cedric on a new computer you do not need to perform these manual upgrade steps.
