Ensure you have access to both Amazon Redshift and Redis. Install necessary tools such as `psql` for Redshift and Redis CLI for Redis. Make sure you have the necessary permissions to read from Redshift and write to Redis.

Use SQL to export the data you need from Redshift. You can do this by connecting to your Redshift cluster using `psql` or a similar SQL client. Run a query to select the data you require and export it to a CSV or a similar file format. For example:
```bash
psql -h -U -d -c "\COPY (SELECT FROM your_table) TO 'your_data.csv' CSV HEADER"
```

Open the exported CSV file and review the data. Clean the data as needed to ensure compatibility with Redis. This could involve removing unnecessary columns, handling null values, or converting data types.

Redis commonly uses a key-value format or data structures like hashes, lists, and sets. Transform your data into a format suitable for Redis. For example, you might map each row of your CSV to a Redis hash, where the primary key column in your CSV becomes the key in Redis.

Ensure that the Redis CLI is installed on your system for data loading. Connect to your Redis server using the CLI. For example:
```bash
redis-cli -h -p
```

Using a script (e.g., Python, Bash), read the transformed data from the CSV file and insert it into Redis using appropriate Redis commands like `HMSET` for hashes. Here's a basic Python example:
```python
import csv
import redis

r = redis.Redis(host='', port=, db=0)

with open('your_data.csv', mode='r') as file:
csv_reader = csv.DictReader(file)
for row in csv_reader:
key = row['id'] # Assuming 'id' is your primary key column
r.hmset(key, row)
```

After loading the data, verify that it has been correctly inserted into Redis. Use Redis CLI to check the data. For example, use `HGETALL ` to retrieve all fields and values of a hash stored at the specified key. Confirm that the data matches what you extracted from Redshift.

By following these steps, you can manually move data from Amazon Redshift to Redis without using third-party connectors or integrations.
