You can very easily import groups from an old database to a new one. These processes are described in the HyperSizer user's manuals.
Open the HyperSizer Basic Users Manual (from within HyperSizer, go to Help | User Manuals | User Manual Basic) and search for:
'Import the "Answers" Workspace'
'Import Workspaces'
'Store and Retreive Groups'
Also for projects that depend on FEA, go to the PRO manual and search for:
'Importing a Project'
Let me know if you need more detailed information.
