Hi @sns ,

follow these steps to create a VM based on an existing managed disk:

• Navigate to Disks in the Azure Portal
• Find the OS Disk of the deleted VM (enter the name of the VM in the filter)

The Owner property of the disk should be -

• Click on the disk
• Select Create VM

• Follow the Create a virtual machine wizard and select the Virtual Network and Subnet you want the VM connected to.

Hey @sns

From another similiar post (answered by AndreasBaumgarten)

It's not possible to switch a VM between subnets/vnets without deallocating/deleting-recreating.

Easiest way:

-Delete the VM but keep the OS Disk.
-Deploy a new VM in the new subnet and use the still existing OS Disk.

Hi @sns ,

because sometimes the wording of virtual network, vNet and Subnet is mixed:

A Virtual Network (vNet) contains 1 or more Subnets
A Virtual Machine (VM) is connected at least with 1 Subnet in 1 Virtual Network (the VM is not directly connected with a Virtual Network. Instead the VM is connected with a Subnet of a Virtual Network)

For instance:
Azure Virtual Network: 10.2.0.0/16 address space

Same Virtual Network with 2 Subnets
Within the same Virtual Network with 2 Subnets the VM can be connected to a different subnet without deleting/recreating. The "delete and recreate approach" isn't necessary )

Different Virtual Network
If you want to connect the VM with a Subnet in a different Virtual Network you have to follow these steps:
-Delete the VM but keep the OS Disk.
-Deploy a new VM in the new subnet and use the still existing OS Disk.

Hi @sns ,

yes, just delete the Network Interface and the Public IP. Keep the OS Disk.

During the deployment of the new VM select the Virtual Network and the Subnet on the Networking tab you want to connect the VM to.

Answer 5

Hi @sns ,,

please try to ping VMONE from VMTWO.
please try to ping the domain name snstelangana.com from VMTWO
In both cases you should get a positiv result.

Verify the DNS settings of the "old" subnet/Vnet and the "other subnet/Vnet"
Are both VMs in the same Subnet in the same vNet?
