Migrate Your Elasticsearch Data to Alibaba Cloud Using Logstash

Alibaba Cloud's Elasticsearch service offers a powerful, scalable solution for search and analytics workloads. Migrating data from a self-managed Elasticsearch cluster to Alibaba Cloud's managed service can be a daunting task, but with Logstash, the process is simplified and secure. This article demonstrates how to execute this migration effectively and addresses prerequisites and steps, ensuring smooth data synchronization.

Prerequisites

Before moving ahead, ensure the following:

Both Logstash and Elasticsearch clusters are operational.
elasticsearch input and elasticsearch output plugins are installed in Logstash.
The version compatibility between the self-managed and Alibaba Cloud Elasticsearch clusters has been verified.

Migration Strategy with Alibaba Cloud Logstash

Step 1: Preparation

1）Ensure your self-managed Elasticsearch cluster is hosted on Alibaba Cloud ECS instances within a VPC.

2）Create an Alibaba Cloud Logstash cluster and configure it within the same VPC.

# Consider using Alibaba Cloud ECS instances for your Elasticsearch deployment, follow:
# https://www.alibabacloud.com/help/elastic-compute-service/latest/install-and-run-elasticsearch

3）Deploy an Alibaba Cloud Elasticsearch cluster with Auto Indexing, following:

# Follow the guide to create and set up your Alibaba Cloud Elasticsearch cluster:
# https://www.alibabacloud.com/help/elasticsearch/latest/create-an-alibaba-cloud-elasticsearch-cluster

Step 2: Configure and Run a Logstash Pipeline

Configure your logstash.conf with the input from your self-managed cluster and the output to your Alibaba Cloud cluster.

input {
  elasticsearch {
    hosts => ["http://<self_managed_cluster_IP>:9200"]
    user => "elastic"
    password => "<your_password>"
    index => "*,-.monitoring*,-.security*,-.kibana*"
  }
}

filter {
  # Add any filters here if necessary
}

output {
  elasticsearch {
    hosts => ["http://<alibaba_cloud_cluster_endpoint>"]
    user => "elastic"
    password => "<your_password>"
    document_id => "%{[@metadata][_id]}"
  }
}

Replace and with your respective cluster information.

Step 3: Deploy and Observe Results

1）Through the Alibaba Cloud console, deploy your Logstash pipeline and observe the migration process.

2）Access the Kibana console to verify data synchronization success.

# Verify index migration in Kibana
GET /_cat/indices?v

Final Notes and Recommendations

Perform the migration during a low traffic period to minimize impact.
Test your pipeline with a subset of data before migrating the entire dataset.
Monitor the migration closely for any errors or inconsistencies.
