GCP - Copying VMs between projects

These days at work, I had to move some virtual machines (VM's) between different projects.
After doing a quick search and spending some time, this was the result.
Hope this helps you too.

Before you begin

• Be familiar with gcloud cli
• Any questions, consult the gcloud reference

How to copy VM with single boot disk

1. Create a snapshot of persistent disk:
   

   gcloud compute snapshots SRC_SNAPSHOT_NAME \
       --source-disk SRC_DISK_NAME \
       --source-disk-zone ZONE \
       --project SRC_PROJECT
   

2. Create a disk image from snapshot:
   

   gcloud compute snapshots SRC_SNAPSHOT_NAME \
       --source-disk SRC_DISK_NAME \
       --source-disk-zone ZONE \
       --project SRC_PROJECT
   

3. Create the virtual machine:
   

   gcloud compute instances create DST_VM_NAME \
       --image-project SRC_PROJECT \
       --image SRC_IMG_NAME \
       --project DST_PROJECT

How to copy VM with boot disk and, at least one, attach disk

1. Create snapshots from persistent disks:
   

   gcloud compute disks snapshot BOOT_DISK_NAME DATA_DISK_NAME \
       --snapshot-names SRC_SNAPSHOT_NAME_BOOT,SRC_SNAPSHOT_NAME_DATA \
       --zone ZONE \
       --project SRC_PROJECT`
   

2. Create the disk image from boot snapshot:
   

   gcloud compute images create SRC_IMG_NAME_BOOT \
       --source-snapshot=SRC_SNAPSHOT_NAME_BOOT \
       --storage-location=ZONE \
       --project=SRC_PROJECT
   

3. Create the disk image from data snapshot:
   

   gcloud compute images create SRC_IMG_NAME_DATA \
       --source-snapshot=SRC_SNAPSHOT_NAME_DATA \
       --storage-location=ZONE \
       --project=SRC_PROJECT
   

4. Create the virtual machine using boot disk image:
   

   gcloud compute instances create DST_VM_NAME \
       --image-project SRC_PROJECT \
       --image SRC_IMG_NAME_BOOT \
       --project=DST_PROJECT
   

5. Create persistent disk from data disk image:
   

   gcloud compute disks create DISK_NAME_DATA \
       --image-project SRC_PROJECT \
       --image SRC_IMG_NAME_DATA \
       --project=DST_PROJECT
   

6. Attach data disk into the instance:
   

   gcloud compute instances attach-disk DST_VM_NAME \
       --disk DISK_NAME_DATA \
       --project=DST_PROJECT
   

7. Mount the new disk:
   

   # connect to the instance
   gcloud compute ssh DST_VM_NAME --zone ZONE --project GCP_PROJECT
   # change to root user
   sudo su
   # indetify the new disk (probably will be 'sdb')
   lsblk
   # create new folder
   mkdir /FOLDER_NAME
   # mount the disk
   mount -o discard,defaults /dev/sdb /FOLDER_NAME
   # check files
   ls /FOLDER_NAME/
   # add write permission for all
   chmod a+w /FOLDER_NAME
   # create new entry to fstab
   echo UUID=`sudo blkid -s UUID -o value /dev/sdb` /FOLDER_NAME ext4 discard,defaults,nofail 0 2 | sudo tee -a /etc/fstab
