he has never stated if he's using the site to site transfer, i use this program for local to site transfers all the time and you need NOT the FXP option to use flashfxp...
if he IS doing site to site, sure he'll need that... if it's THAT big of an issue to get things moved... it'd make far more sense to just pull files to local and push to new server in the meantime while trying to figure out the site to site integration
also, on your quote of my response... yes, it is an ftp program... whether it's fxp or not, site to site or local to site is still ftp 😛
