Perhaps consider obtaining a ticket to your portal, as it could be the optimal solution. However, I believe there are several other Cloudlinux customers who share the same inquiry as me.
 
Are there any specific rationales that prevent the concurrent utilization of CL OS Shared and CL OS+ on your portal?

It appears that the only available option is to upgrade all current licenses to OS+.
Regrettably, this approach does not prove to be particularly efficient for my client's licensing requirements.

Indeed, I have observed that CloudLinux has discontinued the standard license, which is unfortunate. In the past, I enjoyed favorable pricing as an early adopter.

Currently, their sole offering is OS+. However, the standard OS can still be obtained through a cPanel partner, albeit at a higher cost compared to before.

It's worth considering alternative options and exploring different providers to ensure the best value for your investment in the long run.

It's like they're forcing us to ditch CL OS Shared without a shred of flexibility in the portal. This ain't cool for peeps juggling diverse client needs-total buzzkill on the efficiency front. Is there some shady tech limitation or just a cash-grab scheme behind this?
