Transfer a backup ROM to a new replacement device

[jokkerb]

I spider webbed my DroidX a few days ago, and got the Asurion replacement today. Instead of going through the laborious process of backing up all my apps +data +incidentals, wouldn't it be easier to backup and save my old device as a ROM, then restore that ROM to my new device? Is this possible? I've been using google-fu but haven't been able to find a post that deals with transferring a ROM across 2 devices. Thank you.

My problem just got more complicated,

The replacement droidx is running 621, which makes it hard to root. I don't mind running through the process of rooting it, but can I just flash my backup ROM from the old droidx to the new droidx from my computer? And if I can flash my droidx using a computer, how much risk of bricking my phone is there?

You'll have to root and flash your ROM from SD.

ok, so root with the 621 method, then use custom recovery and flash my saved rom right?

Right.
