I have a customer that has multiple websites. They have one with a Miva Merchant account through www.dotcomdesigners.com (http://www.dotcomdesigners.com). They would like me to hand this account and have it transferred to my server but I am a little troubled on this one. It appears that dotcomdesigners offers them a Mivamerchant package. I don't know how their package is setup to just transfer them over.

Does anyone have any experience in doing this that could give me a few tips or am I just better off leaving it at the other host?
