I thought I've heard you can do that but when I called today they said you can only do business card to business card and personal to personal. Is this one of those things that you need keep calling to get the right person who knows what they're doing or can they really not move available from business to personal? It's personal guarantee business card.
As far as I know you can't move business limits to a personal card.
Some lenders like American Express allow you to move personal limits to a business card but not vice versa.
Concur with the above replies.
Business limits are typically kept separate from personal.
