Upgrading from a previous DAS release
To upgrade to the latest DAS/DAS-Lite release, you must upgrade the DAS cluster components (the DAS Webapp and the DAS Event Processor) on all the hosts on which you have installed DAS/DAS-Lite. If your DAS clusters are managed by DP, then you must also upgrade the DAS-DP App that is installed on the DataPlane host.
The supported starting points to upgrade to the DAS/DAS-Lite 1.3.0 release are DAS 1.2.0 and DAS 1.2.1 releases.
You can follow the instructions in this guide to upgrade from either the DAS 1.2.0 or the DAS 1.2.1 release.
