Hello, 
the Lansweeper 3.5.2 (Service, Database; Web) is installed on old server. 
I want to migrate the Version 4 to an new server, so i only moved the existing database to the new server and tried to install the new lansweeper version. 
I also want to migrate from SQLExpress2005 to SQLExpress2008. 
Migrated database seems to work fine, because i can access it from webconsole without any problems. 
Thanks
Daniel
