2002 is almost ancient history on the Internet, you could try to make your customers aware of change, not just their site, their computers, but those of their customers/visitors of their website.
If you do that from day 1, it's much easier 7 years later to remind them: I'd like to offer my services and give your website a virtual "new layer of paint", it's currently showing it's old age and could do far better.
If possible add in things they might have liked back then but that were far beyond the status of browsers then [oops: IE6 is that old isn't it ?], or show them similar upgrades you did for other customers (before/after).
