Description :- If you have an instance in your project and you want to update its machine type. For this you have to install Google Cloud SDK.

Steps:-

1) Delete the instance that you want to upgrade by keeping its boot disk.

     gcloud compute instances delete <instance-name> --keep-disks boot

2) Now create image from this boot disk

     gcloud compute images create <any-image-name> --source-disk <instance-name>

3) Now Check Images list

    gcloud compute images list

4) Now Create new instance from developer console or using gcloud compute

   and select your image as boot disk.
