Implementing Data Migration Pipeline without Deployment Manager

Hello Community Members,

We are trying to implement data migration pipeline to get production sample data to Business Operation Environment for simulation. We faced an issue after configuring the artifacts needed using the steps provided here: < https://academy.pega.com/challenge/preparing-data-migration/v1 >. Specific issue we faced is when running “Export case type” in development environment for unit testing, we came across “No valid keystore instance found” issue. Any input on this?

Note: we are not using deployment manager for our implementation. The environment details are: Pega platform: 8.6 and CDH:8.6

we were able to resolve this specific issue by deleting generated artifacts (Datasets and Data flows) and regenerate them again. Also, we had to uncheck "stream processing " option on the dataset.
