You can assign block storage to a different cloud server at any time. You may need to subsequently adjust the configuration of the data storage medium in your server's operating system. To assign block storage to a different cloud server, proceed as follows:
You are in the Infrastructure > Block Storage section.
You have not combined the boot partition and the block storage into one volume.
Please note: If you have combined the boot partition and the block storage into one volume and assigned the block storage to a different cloud server, inconsistencies in the file system can occur, causing the server to become inaccessible.
Select the desired block storage.
Click next to Assigned to:.
Select the server to which you want to assign the block storage.
Click Save Changes.
The server is assigned.
