[SOLVED] Question on Proxmox Storage

[Halo.Wings]

Hi Everyone,
New to Proxmox (have a VMware background) and I am in the process of looking for an alternative to VMware.
Running 3 nodes on 7.2 and one NAS (Rocky Linux 9) connected to a 1 GB switch (local network/NAT).
I have two VMs running (both Windows 10) and I have noticed that when I migrate them between the nodes (P1, P2, P3) each time I migrate the running VM, there is a new qcow2 file created that is the full-size of the original VM that was migrated. It is given the name of the VM-0, VM-1, VM-2, VM-3, VM-4, etc...
I can remove the files so I do not think they are in use.
I was just wondering if this is normal behavior or not?
I have a 1 TB SSD in the NAS and it is around 60% full with these images (VM has a 60 GB Hard Drive).
If I am going to put Proxmox into production it will have to deal with around 12 TB of VM Hard drives, if I have duplicates the VM files each time I perform a migration then that will mean that I need to purchase a larger NAS for my setup.

Never mind - I figured it out
Sorry.

Please be so kind as to explain your solution and mark the thread as solved, so others with the same issue can find it.

The solution to this is to simply remember to delete the old disk image when moving a VM between storage mediums. Not something that I was expecting, but now that I know I will add it to a checklist I have for when I need to move VMs between servers with just local storage.

FYI, in the GUI, there is a checkbox to delete the old disk image after move
