# Migrate VM or LXC from one volume to another
|
|
|
|
If you messed up and placed your VM or LXC on the wrong storage type, this will help for migrating to the correct storage.
|
|
|

|
|
## LXC volume migration
|
|
|
|
LXC migration must be performed on a **stopped** LXC.
|
|
|
|
For the sake of this example, we are using LXC vmid 205.
|
|
|
|
Find the available storage name you want to migrate to first:
|
|
```
|
|
pvesm status
|
|
```
|
|
|
|
Verify the name of the current volume the LXC is contained on:
|
|
```
|
|
pct config 205 | grep rootfs
|
|
````
|
|
|
|
The output of my available volumes:
|
|
```
|
|
root@pve:~# pvesm status
|
|
Name Type Status Total Used Available %
|
|

|
|

|
|

|
|
nvme lvmthin active 3873329152 1028756222 2844572929 26.56%
|
|
pi2 cifs active 13563452384 1357229972 12206222412 10.01%
|
|
smb cifs active 6188571648 860594176 5327977472 13.91%
|
|
```
|
|
|
|
Once you verify the lvmthin volume, in this case `nvme`, begin the migration:
|
|
|
|
```
|
|
pct shutdown 205
|
|
pct move-volume 205 rootfs nvme
|
|
pct start 205
|
|
```
|
|
|
|
1. Shutdown the container
|
|
2. Move the container volume to the new lvmthin storage device
|
|
3. Start the container
|
|
|
|
**Notes:** The old storage device will still be connected to the LXC, labeled as `unused disk 0` and will need to be manually deleted to recover the storage space.

## VM volume migration
|
|
|
|
VM migration is easier and can happen **live**.
|
|
|
|
Example:
|
|
- `vmid 800` - VM ID number
|
|
- `storage scsi0` - VM storage device (hardware tab, hard disk # ID)
|
|
- `nvme` - target storage
|
|
- `--delete 1` - delete source volume
|
|
|
|
```
|
|
qm move-disk 800 scsi0 nvme --delete 1
|
|
``` |
