Hi, friend!
I don't think it's necessary to re-install, but if you do. You need to uninstall the database and imaster software installed on the server. Then download it from the official website again. In addition, we need to set the license to the invalid state on NCE-Campus, roll back the license to the ready state on the ESDP platform based on the revocation code, reinstall NCE-Campus, and use the new ESN to activate the license. Then, import the license to NCE-Campus. For installation steps, you can also refer to the links below.
