Orphaned data files

Orphaned data files

Hi All

Backstory:
Couldn't get ManageEngine Netflow to start this morning (running on Windows) after many failed attempts. I ended up uninstalling v11 and installing v12 and what ever the issue was went away and app is running as expected.

Question:
Can I import the data files from the old installation example (C:\Program Files\ManageEngine\OpManager\data\Router_50001\20191126141558398_5000001.txt) into the new installation? 

Thanks for any help offered.
