How to migrate sharepoint 2007 document library to Sharepoint 2010 with Document level permission..

Hi,

There is a need for me to Migrate SharePoint 2007 document library from SharePoint 2007 to SharePoint 2010.

In my SharePoint 2007 document library permissions are set on document level.

Is it possible to migrate SharePoint 2007 document library with document level permissions?
