Clustering between a physical server DASD and a VM

Scenario :

Physical Server (PS1) with DASD : WIndows 2012 R2 (Multiple terabytes of data on multiple partitions/drives)

Virtual Server 1 (VS1): Windows 2016 (target server Day 1)

Virtual Server 2 (VS2): Windows 2016 (target server Day 2, once all data is synced with VS1 PS1 will be decommissioned)

In the past I have created clusters but with new shared drives with 0 data on them on day 1. 

Now the challenge is to create a cluster without creating a new drive but to use an existing drive on PS1 and replicate the data to VS1 and then later to VS2 (in shared mode) and then decommission PS1.

All this without losing PS1 service availability and not erasing data at the source server.
