Can I use migration assistent from a other disc only with USB2 connector?

[kolo]

I wil get a new MBP next week. Unfortunately, I can't migrate from my old MBP to a new one directly but only from my backup on other disc, which doesn't have FireWire.

Apple instructions are:
You can connect your Macs in one of four ways to transfer information with Migration Assistant:
- FireWire or ThunderBolt
- Wireless (Wi-Fi) or Ethernet

There is nothing about USB2 . My migration should be from Snow Leopard 10.6.8 to OS X Lion. Should I be worry how to do it? Any suggestions? Thank you.

I did it from USB and it worked fine.
