Rebuild site, loose links?

[Vietnamese robot]

Hello everyone,
I am plan to rebuild one of my site with different website software, I have more than a thousand links now, my question are do I have to inform other sites that I have changed my link pages or if I just keep changing it, what happen then? all my links will be dead?
Thank you for youe input in advance. thank you for your previous advices, it works!

I changed management software for a couple of sites last year. It was scary but I survived! The content didn't change much but hundreds of URLs changed. Google rankings disappeared for a while, but within a month most of the new URLs were within a rank or two of where the old ones had been. Yahoo was slower to catch up, though.

Here's what worked for me:

• Set up 301 redirects from all old URLs to the new equivalents. All of them, no exceptions.

• Make sure every link you control is updated. Again, no exceptions. Old links within your own network seem to cause more confusion than old links from outside sites.

• Track down external links pointing to old URLs and ask the websites to update them. Give them all the details they need to do the task quickly and easily. Some will, some won't, but a few old links don't seem to cause problems as long as they're the minority and your 301's are in good order.

• Work on getting some new links.

• Let a few months pass. You can start removing 301's one by one if you're confident that the old URLs are no longer in circulation anywhere.

Good luck!
