Establish network connections

Network compatibility overview

Express Connect and ClassicLink have usage limits that may affect your connections. Review the relevant product documentation before you begin.

Connect clusters across different VPCs

1. Establish a private network connection between the two VPCs using Express Connect circuits. For details, see Connect to VPCs.

2. Add the IP addresses of both the source and destination HBase clusters to the whitelist of the LTS cluster.

3. Activate Hadoop Distributed File System (HDFS) for both ApsaraDB for HBase clusters.

Connect clusters within the same classic network

LTS does not support direct migration within a classic network. To proceed:

1. Add the IP addresses of both the source and destination HBase clusters to the whitelist of the LTS cluster.

2. Enable the HDFS and HBase ports on both HBase clusters.

Connect a classic network cluster to a VPC cluster

1. Establish a ClassicLink connection for the VPC. Bind the classic network-connected Elastic Compute Service (ECS) instance to the corresponding ClassicLink connection. For details, see Overview.

2. Add the IP addresses of both the source and destination HBase clusters to the whitelist of the LTS cluster.

3. Activate HDFS for both ApsaraDB for HBase clusters.

Connect a classic network cluster to an ApsaraDB for HBase classic network cluster

LTS does not support this network combination directly. Use classic network-connected ECS instances as intermediaries:

1. Purchase several classic network-connected ECS instances.

2. Add the IP addresses of both the source and destination HBase clusters to the whitelist of the LTS cluster.

3. Activate HDFS for both ApsaraDB for HBase clusters.

Connect an ApsaraDB for HBase classic network cluster to a VPC cluster

LTS does not support this network combination directly. Use classic network-connected ECS instances as intermediate instances and release them after migration completes. The ECS instances and the VPC-connected HBase cluster must be in the same region, for example, China (Shanghai) or China (Hangzhou).

1. Purchase classic network-connected ECS instances to use as intermediate instances.

2. Connect the ECS instances to the VPC using ClassicLink.

3. Add the IP addresses of both the source and destination HBase clusters to the whitelist of the LTS cluster.

4. Activate HDFS for both ApsaraDB for HBase clusters.

Ports for migration

Open the following ports on both clusters to allow LTS to transfer data.
