I think you did it correctly. Just incase here are the steps I normally follow:
1- Backup the 3D Application at the first directory, for instance I go into my documents->my 3d apps and right click the directory there and do a send to->compressed folder
2- Backup the database using the MySql Administrator
3- Copy both the zip and the MySql backup file to an external media device such as a USB drive
4- Stop the services on the old computer and mark the service as a manual start (this ensures that the application wont have two servers running it)
5- Create a new 3D application on the new computer and select the existing name of the app in the list of the old computer's app name
6- Let that finish all the way through
7- Unzip the zip file on top of the directory in the new computer
8- Restore the database to the new computer using MySql Administrator
9- Run a complete distribution again (this updates your patch files on the new server)
10- Go into 2D Kaneva, go into My 3D Apps, manage the application, click on the servers list and remove the old server from that list
11- Add the new server to the list using the computers name (right click My Computer and look at the properties to get the name if you dont know it) and make sure the ports match what you have in the defaultserver.xml file in the blades directory.
12- Start the service via services manager and all should be running.
Let me know if this doesn't work and I can help figure out whats going on,
