# Updating DB instances
<a name="timestream-for-influx-managing-modifying-db"></a>

 You can update the following configuration parameters of your Timestream for InfluxDB instance:
+ Instance class
+ Storage type
+ Allocated storage (increase only)
+ Deployment type
+ Parameter group
+ Log delivery configuration

**Important**  
We recommend you test all changes on a test instance before modifying the production instance to understand their impact, especially when upgrading database versions. Review the impact on your database and applications before updating settings. Some modifications require a DB instance reboot, resulting in downtime.

**Using the Amazon Web Services Management Console**

1. Sign in to the Amazon Web Services Management Console and open the [Amazon Timestream for InfluxDB console](https://console.aws.amazon.com/timestream/).

1. In the navigation pane, choose **InfluxDB Databases**, and then choose the DB instance that you want to modify.

1. Choose **Modify**. 

1. On the **Modify DB instance** page, make the desired changes.

1. Choose **Continue** and check the summary of modifications.

1. Choose **Next**.

1. Review your changes.

1. Choose **Modify instance** to apply your changes.

**Note**  
These modifications require a reboot of the Influx DB instance and can cause an outage in some cases.

**Using the Amazon Command Line Interface**

To update a DB instance by using the Amazon Command Line Interface, call the `update-db-instance` command. Specify the DB instance identifier and the values for the options that you want to modify. For information about each option, see [Settings for DB instances](timestream-for-influx-configuring.md#timestream-for-influx-configuring-create-db-settings).

**Example**  
 The following code modifies {{my-db-instance}} by setting a different `db-parameter-group-name`. Replace each {{user input placeholder}} with your own information. The changes are applied immediately.  
For Linux, macOS, or Unix:  

```
aws timestream-influxdb update-db-instance \
    --identifier {{my-db-instance}} \
    --db-storage-type {{desired-storage-type}} \
    --allocated-storage {{desired-allocated-storage}} \
    --db-instance-type {{desired-instance-type}} \
    --deployment-type {{desired-deployment-type}} \
    --db-parameter-group-name {{new-param-group}} \
    --port {{8086}}
```
For Windows:  

```
aws timestream-influxdb update-db-instance ^
    --identifier {{my-db-instance}} ^
    --db-storage-type {{desired-storage-type}} ^
    --allocated-storage {{desired-allocated-storage}} ^
    --db-instance-type {{desired-instance-type}} ^
    --deployment-type {{desired-deployment-type}} ^
    --db-parameter-group-name {{new-param-group}}
    --port {{8086}}
```
