Oracle just released a tool to migrate on-premise Financial Reporting reports for HFM to Financial Reporting reports for FCCS. The tool maps the dimensions, preserves the report formatting and layouts, can convert reports in bulk, and provides ready to use reports. The utility can be enhanced via Python scripting.

Here is the link to the Oracle Cloud Marketplace for the tool:

Looking forward to trying it out!
