Open Source Document Management System | OpenKM

HI, I upgraded community version from 6.3.0 to 6.3.1. The desktop, search, dashboard, all are working except for the Administration tab. The page returns a 404 error /OpenKM/admin/index.jsp. The requested resource is not available. I followed the upgrade instructions here: http://wiki.openkm.com/index.php/Migrat ... 3_to_6.3.1

But I must have done something wrong...any suggestions as to where to look?
thanks in advance

Although I had deleted the folders mentioned in the migration documentation earlier, I just tried deleting again and the admin tab is now working.
thanks...I posted too hastily.

Sure was a problem removing older tomcat cache, sometimes happens ( not always, for it we suggest removing it during the migration process )
