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 1.4.1 release are DAS 1.2.0, 1.2.1, and 1.3.0 releases.
You can follow the instructions in this guide to upgrade from either the DAS 1.2.0, DAS 1.2.1, or the DAS 1.3.0 release.
