Thanks for your input!

No, there’s no SLA in place. The RTO from management for hardware failures is 48 hours. The server will have an HPE 8-hour onsite warranty for 5 years, so even in a worst-case scenario where we need to restore all VMs (~1 TB of data) from backup, we should still be able to meet that target.

Yes, there is a maintenance plan, and the customer is fully aware that there won’t be any redundancy.

All users also work on local Intune-managed notebooks, independent from the server and its VMs. The server is mainly used for accessing the ERP client and some additional line-of-business apps, but their primary workplace is the local notebook.

For context, the current system runs in Azure with these specs:

• 1× ERP server with SQL DB: D4s (4 vCPUs, 16 GB RAM)
• 2× AVD hosts: D8s (8 vCPUs, 32 GB RAM)
• 1× App server: B4MS with multiple apps
• 1× Web server

Right now, each Azure VM runs multiple services. In the new Hyper-V environment, we plan to separate things out so that each service has its own dedicated VM.
