Migration via SolusVM interface¶
Important notes
-
It is not possible to migrate OpenVZ container from SolusVM Master node using SolusVM interface. For such migration - proceed to Manual migration for OpenVZ containers.
-
Due to differences between OpenVZ 6 and OpenVZ 7 - it is not possible to migrate from OpenVZ 7 node to OpenVZ 6 node.
In order to migrate a VPS (does not matter what virtualization) from one SolusVM slave node to other:
1. Open SolusVM > Virtual Servers > VPS_for_migration > Migrate.
2. Select the necessary configuration:
Options explanation:
| Parameter | Description |
|---|---|
| Destination node | The node where VPS should be migrated |
| Migrate Data | Is set to "Yes" - the VPS will be migrated to
another node and location of the VPS will be changed to the new
node in the SolusVM interface Is set to "No" - VPS will not be migrated, its' location will be changed to the new node in SolusVM interface only |
| Compression | Enables compression for transferring VPS data |
| Transfer Speed | Limits network speed used for migration |
| Transfer over Internal Network | Enables transfer between nodes using an internal network. Both nodes have to have an internal IP address configured in node settings |
| Automate on Success | Delete the source VPS and boot on the destination if the migration is successful. If the VPS was suspended it will not be booted on destination.
Note: It is recommended to set this to No and delete it once you have checked the VPS has been transferred successfully. |
3. Click on Start.
4. Wait until the migration is finished.
5. Select what should be done at the end of the migration:
It is recommended to verify that migration is successful and select the corresponding option before finishing migration.
6. Click Confirm.
If there are any errors during migration consider to search for the
solution on our Support Portal,
as it can be documented already:

found
In order to delete the source VPS manually follow the steps:
-
KVM VPS
Use the guide How to remove KVM VPS on the source server manually after migration?
-
OpenVZ VPS
Execute the commands on the Source node:
vzctl stop 101 vzctl destroy 101 -
Xen VPS
Execute the commands on the Source node:
lvremove /dev/yourvg/vm101_imgFor Xen PV also remove logical volume for swap:
lvremove /dev/yourvg/vm101_swap
Note: replace 101 and yourvg with the actual VPS ID and the volume group name.
