Introduction
If your Cires21 license stops working after moving to a new server or changing hardware, the license usually needs to be reassigned or regenerated for the updated machine. This guide explains what information to collect and how to request a new activation so support can validate your installation quickly.
When you need a new activation
A new activation is typically required when the server or device identifiers tied to the license have changed. This can happen after a migration, hardware replacement, virtualization change, or any other update that affects the identifiers used by the license system.
Information to provide to support
To speed up the review, send the support team the updated machine details for the new installation.
- New server name or hostname
- MAC address of the new server or network interface
- Any device ID associated with the installation
- Short description of the change, such as migration or hardware replacement
- If the license was already issued, a short description of the activation error message
How to request reactivation
- Collect the updated server identifiers from the new machine.
- Confirm whether the license was never activated before or was previously working on another server.
- Contact Cires21 support and include the identifiers listed above.
- If you see an activation error, include the exact message or a screenshot if available.
- Wait for support to confirm whether the license must be reassigned or regenerated.
What support may need to verify
Support may compare the new machine identifiers with the license record to confirm that the request matches the current installation. In some cases, the license can be reissued immediately. In other cases, additional verification may be required before a new activation is generated.
Tips for a faster resolution
- Send the request from the technical contact responsible for the installation.
- Include all identifiers in a single message to avoid delays.
- Mention whether the change was planned, such as a server migration, or unplanned, such as hardware failure.
- If possible, keep the old server details available for reference.
Contact support
If you need help with license activation or reactivation, contact Cires21 support through the official support channel or your usual account contact. If your organization uses a dedicated support portal, submit the request there and attach the relevant server identifiers and error details.
