Aws EC2 instance : Change type restricted

I've got 2 t2.large instances which need to be upgrade to t2.xlarge. Problem is that t2.* is not available in the change type drop-list!

I created another instance - like the first one - , I can update to t2.xlarge. I added 2 EBS disk - like the first one -, I can update to t2.xlarge.

Any idea of what can limits the list of available type of instance in the drop-list?!

Solution

  • It was a placement group configuration issue!
