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.

Info

For information on what is new in this release and why you should upgrade, see About this Release.

Note

You cannot roll back the upgrade process. However, it is possible to restore a backup of the previous database so that you can restart the upgrade progress.

titleFresh setup with reindexing

All the index data and configurations are initialized when you start WSO2 DAS 3.2.0 for the first time. Therefore, if your WSO2 DAS 3.2.0 setup is a fresh setup and you want to reindex all the data after migrating analytics tables, you do not need to copy any of the indexing related configurations.

Localtab
titleUsing reindexing command

This method involves running the analytics data backup/restore tool with the -reindexEvents setting to index the data. Here, the indexing is done using the existing data in the database to which you already connected WSO2 DAS 3.2.0 in the Migrating the configurations section. For more information, see Backing Up or Restoring Analytics Data.

titleCopying indexing data

Follow the steps below to migrate the index information from DAS 3.1.0 to DAS 3.2.0.

  1. Copy the contents of the <DAS_3.1.0>/repository/data directory and replace the contents of the <DAS_3.2.0>/repository/data directory with it.
  2. Take copies of the following files in the <DAS_3.1.0_HOME> and use them to replace the new files in DAS 3.2.0 that are in the locations given below.
    • <DAS-3.1.0_HOME>/repository/conf/analytics/my-node-id.dat file
      The following needs to be done when copying this file:
      1. Rename the file to datamy-node-id.dat. 
      2. Copy this file to the <DAS_3.2.0_HOME>/repository/data directory.
    • <DAS-3.1.0_HOME>/repository/conf/analytics/local-shard-allocation-config.conf file
      Copy this file to the <DAS_3.2.0_HOME>/repository/data directory.


Note

Make sure that you do not mix the configuration files between nodes. The configuration files and index data of DAS 3.1.0 - node 1 should be copied to DAS 3.2.0 - node 1, and the configuration files and index data of DAS 3.1.0 - node 2 should be copied to DAS 3.2.0 - node 2 etc.

  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:
    Anchor
    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 wso2server.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 wso2server.sh

...

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

Info

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.
