I don't copy folders I just copy the RDL and all the related solution files which is very important because when changes are made most times only the solution files changes. SQL Server reporting services reports are the easiest to send to others I have emailed and given them to other people in net meeting. This means you move one report at a time and make sure it runs before you move others. This is assuming all your three databases are running the datasource database, reportserverdb and reportservertempdb.
