Problem while replacing SSD on MacBook Air 11

I think you really need to use a different approach than using Disk Utilities imaging service. How about using the Apple Migration service instead. Here you’ll first need to have a bootable external drive running the OS you are currently using. Run the installer and at the end you’ll be greated with the question if you want to migrate your user accounts, apps & data from another system you will want to do this to copy off your stuff to the external drive. Once you’ve done that after you reboot your external drive should be the booting drive. Check your apps and data if everything looks OK, swap out your internal drives and redo the same process. That should do it.
