# Migration to 7.0.0

This guide describes the process of migrating to SDK version 7.0.0

## Step 1

SDK will not accept `url`, `internalUrl` init arguments anymore:

#### Before

```js
Universal({
  url,
  internalUrl,
});
```

#### After

```js
const nodeInstance = await Node({ url, internalUrl });
Universal({
  nodes: [{ name: 'testnet', instance: nodeInstance }],
});
```

## Step 2

Remove deprecated function `setKeypair`\
`SDK` will not accept `keypair` init argument anymore:

#### Before

```js
Universal({ keypair });
```

#### After

```js
Universal({
  accounts: [MemoryAccount({ keypair })],
});
```

## Step 3

Change all of `AENS` method's first argument from `nameId` to `name`

### Before

```js
const client = Universal({ ... })

await client.aensUpdate('cm_ad1wdsa...', ...)
await client.aensTransfer('cm_ad1wdsa...', ...)
await client.aensRevoke('cm_ad1wdsa...', ...)
```

### After

```js
const client = Universal({ ... })

await client.aensUpdate('testname.chain', ...)
await client.aensTransfer('testname.chain', ...)
await client.aensRevoke('testname.chain', ...)
```

## Other Breaking Changes

* Add new compiler `methods` to RPC `communication` (base-app update required)
* Drop compiler version to `version >= 4.0.0 && version < 5.0.0`
* Change node compatibility range to `node >= 5.0.0 && node < 6.0.0`
* Always `verify` transactions before sending them to the node (can be disabled using the option `verify: false`)
