Suggestions Regarding Reporting for Process and Sub Process

Model Changes - Suggestions Regarding Reports for old and new

I have a process with related reports - works well. reports get all data from the single process.

Now I have separated the process into two: a main one and a sub-process.I have changed the reports to select data from the respective process/sub-process - this works well.

What happens when I roll this into Production with the existing data all in one process - the reports will not pick it up.

Should I create a New Process and Sub-Process completely different from the original one, have two sets of reports and two sets of tabs for portal?

Suggestions will be greatly appreciated
