This section explains how to upgrade to DAS 3.0.1 from DAS 3.0.0. For more information on release versions, see the Release Matrix.
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.
Preparing to upgrade
The following prerequisites should be completed before upgrading.
- Make a backup of the DAS 3.0.0 database and copy the
<DAS_HOME_3.0.0>directory in order to backup the product configurations. - Download WSO2 DAS 3.0.1 from http://wso2.com/products/data-analytics-server/.
Reindexing data
DAS versions 3.0.0 and 3.0.1 use the same databases. Therefore, you are able to use the same data by connecting to the same databases as DAS 3.0.0 via configuration files. Once DAS 3.0.1 is connected to the same databases as DAS 3.0.0, you need to reindex the data using the Analytics Data Backup / Restore Tool.
Migrating artifacts
To migrate event streams, event receivers, event publishers, execution plans, scripts, dashboard and gadgets, pack them into a C-App and deploy the C-App in DAS 3.0.1. For more information, see Packaging Artifacts as a C-App Archive.
