  1. Download migration resources from here.
  2. Unzip the migration resources you downloaded and copy the org.wso2.das.migration-3.2.0.jar to the <DAS-3.2.0_HOME>/repository/components/dropins directory.
  3. Copy the .jks files from the <DAS-3.1.0_HOME>/repository/resources/security directory and place them in the <DAS-3.2.0_HOME>/repository/resources/security directory.
  4. Copy the .db files from the <DAS-3.1.0_HOME>/repository/database directory and place them in the <DAS-3.2.0_HOME>/repository/database directory.
  5. If you have created tenants in the WSO2 DAS 3.1.0 environment and if there are any tenant resources in the <DAS-3.1.0_HOME>/repository/tenants directory, copy that content to the <DAS-3.2.0_HOME>/repository/tenants directory.
  6. If you have created any secondary user stores in the WSO2 DAS 3.1.0 environment, copy them from the <DAS-3.1.0_HOME>/repository/deployment/server/userstores directory and place them in the <DAS-3.2.0_HOME>/repository/deployment/server/userstores directory.
