Deletion of old data from web analytics

Can I delete the old data from google web analytics? The sites to be tracked can remain the same.

 

I would imagine it depends on what data that your referring to. If you are looking to delete something specific you may have a problem.

 

yes, should n 't delete u old file , its my idea

 

You cannot delete just certain data. If you delete the entire profile / account then that will delete everything. Really not a good way just to delete certain data. So, in the case that something messes up and data gets skewed for a portion of time - you cannot just remove that portion. Sorry.
