Reload Data after re-configuring variable sampling type

Do you know if I can reload data into a variable after changing its Sampling Type.

My example is: variable originally configured with "Last Good Value". I changed it to "Maximum". If I reload the data (as far back as 2 years), will I get the re-configured data, showing "Maximum" ? If reloading data itself isn't possible, can I re-fire the events using the spserver_cmnaddscheduledtask stored procedure?

Thanks,
