Is it expected that Feature Packs for dedicated licences could be installed on both dedicated servers and VPS?
It is expected. According to Plesk Pricing page:
Plesk license types are based on the operating environment in which Plesk will be running:
- VPS licenses (or also: Virtual Private Server licenses) can be used only on virtual instances based on hypervisor technology such as Virtuozzo, Xen, KVM, Hyper-V, or VMware.
- Dedicated server Plesk licenses can be installed on either a dedicated server or on a VPS (Virtual Private Server).
The same applies to licenses for feature packs.
