This section explains how to upgrade to DAS 3.2.0 from DAS 3.1.0. For more information on release versions, see the Release Matrix.


  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.
  7. If you have created any event receivers and event publishers in the WSO2 DAS 3.1.0 environment, do the following:
    migrate receiver/publisher configurations
    migrate receiver/publisher configurations
    • To migrate the event receiver configurations, copy the contents in the <DAS-3.1.0_HOME>/repository/deployment/server/eventreceivers directory to the <DAS-3.2.0_HOME>/repository/deployment/server/eventreceivers directory.
    • To migrate the event publisher configurations, copy the contents in the <DAS-3.1.0_HOME>/repository/deployment/server/eventpublishers directory to the <DAS-3.2.0_HOME>/repository/deployment/server/eventpublishers directory.
  8. Start WSO2 DAS 3.2.0 with the following commend to perform data migration for encrypted data.
    • On Windows:  wso2server.bat -Dmigrate
    • On Linux/Mac OS:  sh -Dmigrate

  9. Once the migration is successfully completed, stop the server and start it again with one of the following commands.
    • On Windows:  wso2server.bat
    • On Linux/Mac OS:  sh


You should manually deploy Composite Application Archive (CAR) files that you have in DAS 3.1.0 to DAS 3.2.0.


If you have already copied the configurations of one or more event receivers and/or publishers when migrating encrypted data (see Migrating encrypted data - step 7), you can exclude the configurations of those receivers and/or publishers from the CAR file.
