How to change machine type of GCE instance?

Question

As there isn't any direct option to change machine type and i have to create a new instance. What are the steps to do so that the configuration/software that I had installed remain same ?

Answer 1

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.

5) Done.
