Thank you.  
Here my question is simple. I want to update the Topic partition from 2 to 6. How can I do this change from Cloud UI itself?

@mizeintegration As far as I know, you cannot increase the partition count in the Cloud UI. However, you can use the Apache Kafka `kafka-topics.sh` command to alter Confluent Cloud topics.

First you’ll want to create a command configuration file from the Cloud UI. Under the CLI and tools menu you can create a properties file with the proper security settings.

You’ll need an Apache Kafka distribution with access to the `kafka-topics.sh` command. The Kafka quickstart can help you get it installed: [Apache Kafka](https://kafka.apache.org/quickstart)

Once you have the config and properties file locally you can run the alter command like this:

```auto
kafka-topics.sh --bootstrap-server <your-bootstrap-url> --command-config <path-to-your-properties-file> --alter --topic <your-topic> --partitions <num-partitions-to-increase-to>

```

For what it’s worth, you can also use ksqlDB to do this

```sql
CREATE STREAM source WITH (KAFKA_TOPIC='source_topic', FORMAT='<format>');
CREATE STREAM more_partitions WITH (PARTITIONS=6) AS SELECT * FROM source;

```

It’s a similar concept to that illustrated here: [ksqlDB HOWTO: Reserialising data in Apache Kafka - YouTube](https://www.youtube.com/watch?v=sLAztA-rt74)
