## Migrate to different backends
1. Get to the current backend:
```sh
pulumi login
pulumi whoami -v
```
1. Select the stack to export:
```sh
pulumi stack select 'superbros-galaxy2/mario'
```
1. Export the stack's state to file:
```sh
pulumi stack export --show-secrets --file 'mario.stack.json'
```
1. Logout from the current backend, and login to the new one:
```sh
pulumi logout
pulumi login 's3://super-bros/galaxy2'
pulumi whoami -v
```
1. Create a new stack with the same name on the new backend:
```sh
pulumi stack init 'mario'
```
1. Import the existing state into the new backend:
```sh
pulumi stack import --file 'mario.stack.json'
```
1. Check the secrets provider and the key are fine:
```sh
cat 'Pulumi.mario.yaml'
```
## Ignore changes
Add the [`ignoreChanges` option][ignorechanges] to the resource.
```ts
const resource = new.aws.s3.Bucket("bucket", {
}, {
ignoreChanges: [
"tags['last-deploy-at']"
]
});
```
