Discover source data

To discover and collect on-premises data, you can use the AWS Transform discovery tool, AWSMigration Evaluator collector, or upload exports from RVTools and ModelizeIT, as well as AWSMigration Portfolio Assessment (MPA) format exports generated by tools like Cloudamize. AWS Transform can process AWS Transform discovery tool exports as CSV and JSON files in a ZIP file format, RVTools exports as either an Excel file or a ZIP file containing CSV files, and ModelizeIT CSV exports in a ZIP file. For each data source AWS Transform accepts the primary server file individually. However, supplementary files such as connections will only be processed when they are included in a ZIP file with the server files or in an Excel file with the server sheet.

We recommend that you upload the most detailed data available and review your export files before uploading to ensure data completeness and accuracy. Verify that all required files are included in your upload, and confirm that the data reflects your current environment state. This preliminary review helps minimize the need for re-uploads and ensures that AWS Transform can more accurately capture your on-premises environment and better support migration planning, including application grouping and wave planning. You can also incrementally add data as you obtain better data.

AWS Transform automatically detects file format and structure, parses and extracts structured entity records, removes duplicates across multiple files, validates data quality and reports issues, and then prepares a summary ready for downstream migration planning.

After you share and confirm your on-premises data, you can review discovery data by expanding Discover on-premises data in the Job Plan and choosing Inventory readiness summary. You can also ask questions about the data you uploaded to verify that AWS Transform correctly ingested everything or to identify and correct any mistakes in the data processing. For example, you can ask about operating system and versions. If you need to correct mistakes you can re-upload your inventory data from the discovery tool you used, and AWS Transform will automatically process, de-duplicate, and merge the updated records. You can also remove a previously uploaded file if you no longer want to use that inventory data.
