New Linux image naming and registration policies

Introduction

Currently, for each Linux image, there are two series of images, one with a datestamp (e,g, _20180106_0) and one with a _latest name which gets renamed to _prevN and hidden upon a new _latest image registration.

Relocating VMs from one pool to another in OTC

Scope

When you need to scale vertically, i.e. change the available vCPUs or RAM assigned to a VM in OTC, you can use the resize (change specifications) feature and change the flavor of an existing VM.
