Heat update - replaced or not?
Hello, I would like to know, if theres way to tell, which resources will be replaced when running stack update. Mostly interested in knowing behaviour of Nova::server.
For testing ive created stack with 2 vms and immediately ran stack update
$ openstack stack update -e devci1-env.yaml --wait -t prod_ci/sandbox/tonda_test.yaml tonda_test --timeout 3600 --os-project-id d7ab62d3c3f1415ab99b2d2cb9a8de19 --show-nested --dry-run

Why are those resources marked as replaced, even though there are no changes at all? When I run stack update in this state, VMs are not replaced. Update finishes immediately.
When for example I change AZ for those servers, dry run shows the exact same ...
