Prime 2.0 to 2.1 installation

Question

I am currently trying to upgrade Prime 2.0 to 2.1, following the instructions in the release notes.  Having some issues uploading the 2.1 patch to the Virtual controller.  Seems to be a syntax error/fat finger;  Does anyone have any tips or tricks to get the patch uploaded via tftp?  Thanks
Here's the general instructions I was using:
Installing Patches
You may need to install patches to get your version of Prime Infrastructure to the level at which upgrade is supported. For example: If you are currently running Cisco Prime Infrastructure version 1.3.0, you must install the PI_1_3_0_20-Update.4-16 patch before attempting to upgrade. You can check the Prime Infrastructure version and patch version you are running by using the CLI commands show version and show application .
Different patch files are provided for each version of Prime Infrastructure and its predecessor products. Download and install only the patch files that match the version of your existing system and that are required before you upgrade to a higher version. You can find the appropriate patches by pointing your browser to the Cisco Download Software navigator .
Before installing a patch, you will need to copy the patch file to your Prime Infrastructure server’s default repository. Many users find it easy to do this by first downloading the patch file to a local FTP server, then copying it to the repository. You can also copy the patch file to the default repository using any of the following methods:
cdrom—Local CD-ROM drive (read only)
disk—Local hard disk storage
ftp—URL using an FTP server.
http—URL using an HTTP server (read only)
https—URL using an HTTPS server (read only)
nfs—URL using an NFS server
sftp—URL using an SFTP server
tftp—URL using a TFTP server
Step 1 Download the appropriate point patch to a local resource in your environment:
a. With the Cisco Download Software navigator displayed in your browser, select Products > Cloud and Systems Management > Routing and Switching Management > Network Management Solutions > Cisco Prime Infrastructure .
b. Select the version of Cisco Prime Infrastructure that most closely matches the one you are currently using (e.g.,Cisco Prime Infrastructure 1.2 ).
c. Click Prime Infrastructure Patches to see the list of available patches for that version of the product.
d. Next to each patch that is required, click Download , then follow the prompts to download the file.
Step 2 Open a command-line interface session with the Prime Infrastructure server (see Connecting Via CLI in the Cisco Prime Infrastructure 2.1 Administrator Guide ).
Step 3 Copy the downloaded patch file to the default local repository. For example:
admin# copy source path /defaultRepo
Where:
 source is the downloaded patch file’s location and name (for example: ftp://MyFTPServer/pi_9.3.1.0_update.tar.gz).
 path is the complete path to the default local backup repository, defaultRepo.
