Yes! You can use Adobe Analytics data in Adobe Experience Platform. This requires the Analytics Data Connector to be activated and this automatically lands all Analytics data for a report suite into a dataset. You can activate this dataset for Unified Profile and thus make it available for use in Journey Orchestration. These fields will need to be added to the ‘ExperiencePlatformDataSource’ as part of a datapack.
Thanks Russ for describing how you can access Adobe Analytics data from the AEP Profile for orchestrating a journey (evaluating conditions, looking up or computing values to insert as parameters in Actions, etc).
On the roadmap for later in H1 2020 we will add the ability for Journey Orchestration to listen for incoming Analytics events to trigger the start of a journey (or a subsequent step within a journey).
