1. Download ELB 2.1.1.

2. Redo the configurations you made for ELB 2.1.0 in ELB 2.1.1.

   Note
   Note that configurations should not be copied directly between servers. These configuration changes to be done are the same ones you did for ELB 2.1.0. These are typically the changes made to the <ELB_HOME>/repository/conf/loadbalancer.conf file and the <ELB_HOME>/repository/conf/axis2/axis2.xml file. This connects ELB 2.1.1 to your cluster/deployment.

3. Remove ELB 2.1.0 completely from your production environment. This step is necessary as it ensures that ELB 2.1.1 is the version of the WSO2 ELB connected to your cluster/deployment.
4. Start the ELB and restart all other WSO2 Carbon-based servers. See Running the Product for more information on starting the ELB.

Testing the migration

The following are the recommended tests to run on your system.

1. Check to see if the ELB joins the cluster.
2. Send a request to the cluster via the ELB and see if it is distributed to the correct node.
