1.5. Upgrading to a new version
Minor Version Upgrades
To upgrade to the latest minor release of the DataHub version you are currently using:
Go to the Downloads page of the DataHub website.
Check to see if there is a more recent release of the DataHub program than your version.
If so, download it and install it over your existing DataHub installation. The new version will automatically pick up any existing licenses and configuration.
Major Version Upgrades
To upgrade to a major new DataHub release, you need to first contact Cogent to obtain an upgrade license. Then download the latest DataHub archive and follow one of these two procedures:
Upgrade an existing DataHub installation
Install the new DataHub archive over your existing software.
The installer will automatically detect your existing license and configuration. Since your license is not yet valid on this new version, it will not be used, and the DataHub program will run in one-hour demo mode, with all features available.
Select the Licenses option. To see your existing license, check the box.
Install the upgrade license you received from Cogent. The license number of the upgrade license must match the original license. If you have multiple upgrade licenses for several add-on features, install each one, ensuring that it matches its original.
Example: version 7 to version 9 upgrade:
Example: version 9 to version 10 upgrade:

The End User License Agreement stipulates that each DataHub license may be used on only one machine at a time. So you may not use the original license on any other DataHub installation.
Upgrade and move to a new computer
Often part of the upgrade process is to move the DataHub program to a new computer. Please see Section 1.9, “Backing Up or Moving a DataHub Installation” for information on moving configuration and license files.
If you want to use your existing configuration, copy and move it.
Install the new DataHub archive. (You do not need to install the earlier version of the DataHub program.)
Continue with step 2 in Upgrade an existing DataHub installation (above).
