I am in the process of migrating from Exchange 2010 to Exchange 2013.  I have all mailboxes migrated to Exchange 2013 and am ready to eliminate Exchange 2010 in its entirety, but I am unsure about public folders.  We have no public folders other than the default ones generated during the Exchange 2010 installation.  I can't find anything in any of the migration guides that explain what I need to do in this case.  Do I need to migrate anything, or can I just uninstall Exchange from the server and ignore the default public folders?

if there are not PF then it is safe to install unless you have been using outlook 2003.

Thanks.  We had one person using Outlook 2003 years ago, but that has since been replaced with Outlook 2010.  I was able to remove the "Calendar" folder that appeared in the Public Folder Manager (took me a while to see the "Delete" link) and was able to proceed.  It does not appear that I have caused any problems.
