# Migration from archive to full node

Rollup node operators can reduce storage cost by changing the type of rollup node. An `archive` node stores the full state history for each block since genesis block. In contrast, a full node stores the state only for the recent 128 blocks. Therefore, moving from `archive` node to `full` node will significantly reduces the storage needs for running rollup nodes.

To migrate the rollup node from `archive` node to `full` node, take the following steps:

1. Stop the current rollup node. Change current working directory to the root of `setup-rollup` repository.

```
cd setup-rollup
docker compose down
```

2. In `geth.yml`, change `--gcmode` from `archive` to `full` node.

```
--gcmode=full
```

3. Resume the rollup node

```
docker compose up -d
```

Your rollup node should be up now. It will garbage collect the states older than 128 blocks.
