Hi I am running aws eks using pulumi and deployed an helm chart to the cluster. This setup is running in production for the past few months. Today i ran 
pulumi refresh
and update the stack but now every time i try to run 
pulumi up
i see that according to preview pulumi is about to delete all helm chart resources. How can i understand the reason for this ? i definitely don't wont to delete those resources from the cluster
g
Can you provide the detailed diff? It should tell you why it’s planning to replace the resources.

This is 
pulumi up

I don’t see anything obviously wrong in the diffs you provided. A couple possibilities I can think of would be changes to the
Copy code
eks-k8s-concourse
Provider you’re using, or something in the program changed. Does it show that the resources will be replaced, or simply deleted?
q
just be deleted without any more data
before the 
pulumi refresh
command all was working
is there a way to revert 
pulumi refresh
command ?
g
You can revert to the checkpoint state before the refresh using 
pulumi stack export --version=<previous-version-number> > stack
and then 
pulumi stack import --file stack
You can also download any checkpoint state from the Pulumi console if you’re using the SaaS and then import it with the same import command
q
Ok nice i will try that 🙏
