25.4 Release Notes

# Licensing

An upgrade to IDOL version 23.2 from a previous major version, such as IDOL 12.x or IDOL 11.x, requires a new license. Please contact OpenText and request a new license key.

IMPORTANT: You must update your License Server to version 23.2 or later to license components with the upgraded license.

## Versionkey.dat

IDOL 23.2 and later builds require you to include a new supplementary `versionkey.dat` for licensing.

You can obtain the `versionkey.dat` from the Software Licenses and Downloads portal (SLD), in the License Server package or as a standalone download package.

IMPORTANT: Software downloads from other locations (for example, Docker images from docker hub) do not include the `versionkey.dat`. You can obtain it only from the central SLD portal.

If IDOL cannot find the version key, or if it is invalid, IDOL does not start. In this case, details are provided in the `license.log`.

To use the version key:

- For a standard License Server deployment, place the `versionkey.dat` alongside your `licensekey.dat` file when you run License Server.

- For IDOL OEM deployments, deploy the `versionkey.dat` alongside the `licensekey.dat` with the component.

- For the Eduction SDK, concatenate the contents of the `versionkey.dat` to your license key with a semicolon (`;`). For example, if your license key is `ABC123` and the version key `XYZ999`, then the final license value is `ABC123;XYZ999`.

- For the edktool command-line tool, add `versionkey.dat` file to the same directory that you supply in the `licensefile` parameter.
