If your second server has no custom reports (all your custom reports are on your first server) then you can copy the entire BXDATA folder and move it to your second server. This is essentially replacing all reports, folders, reporting trees, etc. to be exactly the same as the first server. However, if you have any reports or customizations on the second server that you want to keep, you need to do the exporting and importing suggested by Jim. Always good practice to rename the second server's BXDATA folder to BXDATA-OLD just to have it around. That way in case you need it back, you just have to switch the names and it will be as it was before the file switch.
