Help with Migration - Physical to Azure VM

I need help with this situation.

My ultimate goal... our MSP hosts a VMWare network. They won't assist with transferring the VM, so I want to do a agent-based migration from the Windows Server VM (which I am the admin of) to Azure.

I'm attempting to follow the Azure Migration flow, i guess using the "new" experience. I created the replication VM on a HyperV VM inside our LAN, which ran the Discovery.

Now I'm creating a wave for an assessment of a lift-and-shift plan. But the Wave wants me to install DRInstallation on the same migration VM, but it won't install because the earlier Azure Migration Installer software is installed on this VM.

Am I missing something? Did I run a step out of sequence? The error is: "This host has already been used as DR Appliance. Aborting the installation..."
