[ovirt-users] Ovirt standalone engine ssl cert is about to expire

Need some help with the renewal of the ssl certificate (I believe it is a self-signed cert )that is about to expire in a month, this is a standalone ovirt engine running software Version:4.3.4.3-1.el7. The certificate was good for 5 years and it is about to expire. As I understand correctly, this certificate is for the https access for the management page. Can this be done on a running system without affecting any hosts or VMs? Any instructions for the standalone ovirt engine scenario that you guys can share? Thanks a lot, Software Version:4.3.4.3-1.el7
