Changing an Azure virtual machine size

Prev Next

You can change the size of a Network Security or Central Management System virtual machine if you determine that is over-utilized because it is too small, or under-utilized because it is too large.

Important

After you change the size of a Network Security virtual machine, you must restart the virtual machine twice for the change to take effect.

To change the Azure virtual machine size:
  1. Log in to the Azure console.

  2. Stop the virtual machine:

    1. Select the virtual machine.

    2. Click Stop.

  3. Change the virtual machine size:

    1. Click Size under Settings.

    2. Select the new size and click Resize.

  4. Start the virtual machine:

    1. Click Start.

    2. Wait for the virtual machine status to be Running.

  5. (Network Security virtual machines only) Reload the virtual machine:

    1. Log in to the Network Security CLI.

    2. Reload the virtual machine:

      hostname (config) # reload
                           

    Important

    This step is mandatory because the virtual machine must be started and then reloaded for the change to take effect.
