Hi Rahul,
Please refer below bullet points:
- Migration of powered-on virtual machines with snapshots cannot be performed in ESX/ESXi 3.x and ESX/ESXi 4.x. You must either delete the snapshots or power off the virtual machine before the migration.
- Migration of powered-on virtual machines with snapshots is supported in ESXi 5.0 and later.
Ref:VMware KB: Migrating virtual machines with snapshots
Also refer:Migrate VMs with snapshots - Yes, in vSphere 5 - ESX Virtualization
You can use advanced tab for the VMs having snapshot.
Once you click on advanced tab : You will get 2 types of files.
1. Configuration file
2. List of VMDKs files.
Your snapshot would be part of "configuration file". Hence you can keep on VM config file on separate DS
