How to upgrade ubuntu in side virtual box installed using vagrant?

Question

I have Ubuntu 14 installed to my virtual machine(Virtual Box) using vagrant. Now I want to upgrade it to Ubuntu 16.

I have an ISO image of Ubuntu 16 with me. Is it possible to upgrade to latest version using this image or I have to use some other approach.When I go to setting and select usb it is disabled and I am not able to enable it.

If I run following command sudo do-release-upgrade it says no new release found.

Please guide me.

Upgrades between LTS releases are not enabled by default until the first point release, 12.04.1/14.04.1, scheduled for July/August. It is recommended that most LTS users wait until then before upgrading — Elder Geek, Jun 07 '16 at 02:46

You can attach the ISO image to the virtual box and the upgrade dialog should pop up. Also you can use the upgrade via Internet (upgrade manager) from within the Virtual Box.
