Maximo Open Forum

Hello experts, I am new to *Maximo Application Suite on Cloud (SaaS)*. I need to migrate full production data from an on-premise Maximo 7.6.1.3 (Oracle DB, 10+ years in use) to the SaaS environment, with a total volume of *over 50 million records*. Since I have no access to the SaaS DB2 server or operating system, IBM support recommended importing data via S3 using cron tasks, following this guide: https://www.ibm.com/docs/en/masv-and-l/maximo-manage/cd?topic=data-importing-s3-by-using-cron-tasks However, the documentation is very brief. I have completed the configuration as instructed. The cron task runs *without any errors*, but *no new data is created in the system*. I hope to get advice from experts who have real experience with this method: 1. Why does the cron task show no errors but import no data? 2. The guide does not mention *data mapping*. Does the system automatically map CSV columns to the corresponding database fields? 3. After a successful full import, what is the standard way to *validate data completeness* and ensure no records are missing or incorrect? Any help or shared experience would be highly appreciated. Thank you!
