ResolutionIn order to change a Parallels Plesk Panel (PP) license to a PP-Concerto license, it is necessary to terminate the existing PP license in KA, or to wait until the original PP license expires. If the license is terminated or expires, Parallels Plesk Panel will install the PP-Concerto license automatically.
In order to forcibly change a PP license to a PP-Concerto license, it is necessary to move all files from the /etc/sw/keys/keys directory to another directory, e.g., /root/keys/.
# mv /etc/sw/keys/keys/* -t /root/keys/
After moving the files, log in to the Control Panel. Parallels Plesk Panel will detect the Concerto environment, and the PP-Concerto license will be issued automatically.
