Are the subnets created automatically by your cloud provider, or implicitly by a sophisticated resource like

awsx.ec2.Vpc

? Or are they simply already existing and unmanaged?

You have a few options, but they all sidestep Pulumi, because Pulumi cannot manage (== delete) unmanaged resources, and it cannot delete some things before it creates other things.

they are managed by pulumi, aws.ec2.Subnets specifically.

I have a config that is used to input what subnets we want to create.

If I remove all entries from that config and replace them with new ones, instead of destroying the old ones and then creating, it creates first

That is intentional, to help with zero-downtime updates. The Pulumi docs about autonaming covers the topic: https://www.pulumi.com/docs/intro/concepts/resources/#autonaming

To manage this in your case, if it is once-off, you could make the changes and comment the relevant code out, then `up`: this will delete the old vresions; then put the code back and

up

Another option is to rework into separate projects or stacks, and use

destroy

and

up

appropriately.

Finally, you could ensure that the Pulumi name of the resources doesn't change. Pulumi will attempt to update rather than destroy/create.
