This method is recommended for instances with ephemeral storage less than 150GB in size. For instances with storage larger than that, creating new instances in Arbutus Cloud and copying the required data across from West Cloud is preferred to creating Glance images and transferring the images between clouds. In either case you will still need to copy data from any non-boot ephemeral storage (i.e. mounted under <code>/mnt</code>) separately.
