updating websites

My company wants to update clients' websites. These websites were designed by other companies, using a variety of software - everything from FrontPage to HomeSite to GoLive. We have GoLive 5.0. I have the most web knowledge (one website designed in Dreamweaver, no coding experience) so I have been designated to research this. If I download a website that was created in another program into GoLive, make changes, then upload it, will the site still work? Is this a really bad thing to get into if I don't know HTML? Where can I get information about this?
Thanks!

>>will the site still work?
As much as it ever did... See, the main downside of all wysiwyg editors is that they are as incompatable with different versions of browsers as they can get. It's like they have have of the dev team just sitting on their behind and thinking how to mess it up.

HTML is HTML no matter what editor you use. The problem is that some HTML only works in some browsers, which is what AlCapone is saying. When you make a page in Frontpage, for example, it's still an HTML file, not a Frontpage file. If you open it in Dreamweaver, GoLive, whatever, it can still be edited and saved because it's still just HTML (it's just that some of that HTML may only work in say, Internet Explorer). The real trick to making pages is getting several browsers to test your pages on. I reccomend yout get at LEAST the latest versions of Opera, Mozilla, Netscape, and IE. Then, when you make a change to page, look at it in each of these browsers to make sure it looks good. It it doesn't, edit it until it does.

The place you'll really run into a problem here is if you have a website that was originally made in Frontpage. Frontpage is evil and it lets you use all sorts of nice HTML that only works in Internet Explorer. Problem is, when you look at the page in IE, it looks good. When you look at the page in anyting else (including an edior) it looks like s***. If you get to a site like this, you'll just need to edit it until you get out all of the "bad" code that other browsers can't use. On top of that, Frontpage formats HTML in the freakiest way imaginable so that, even if you only use code that works in all browsers, the damn thing just sort of sprays the code across the page so that when you're looking at the HTML it looks like a tornado hit it. That's not much fun trying to read..
