Update Bootcode

[bfl1]

I'm going to update the bootcode on a VPN concentrator. The file name is vpn30xxboot-4.0.Rel.hex. During the upload it was complaining about improper file name. So, in order to upload the file, I renamed it to vpn304Rel.bin. Before I finish the bootcode update, do I need to rename it to something else? Is it expecting a certain pattern?

Any help is appreciated.

The CCO website has the file to be downloaded named vpn30xxboot-4.0.Rel.hex. I have renamed it in order to upload it to the concentrator. Now that it is on the concentrator, named vpn34Rel.hex, I've tried renaming it to vpn30xxboot-4.0.Rel.hex, but get invalid file name. Any ideas? I need to do the update today, so any suggestions are appreciated.
