It is recommended that you backup the certificates on the central node in a Qlik Sense site so that they can be restored, if needed.
The backed up certificates can be used for different purposes:
- Restore the certificates on the same node as they were exported from.
- Move a node to another node in the Qlik Sense site. This means that the repository database and its associated crypto key are reused on another node, but with new certificates for communication.
