Sent new Router- will I have to do complete re-set up?

[wine4don]

I just got a new router to replace a 12 year old westell(still not sure why I had to PAY for a old one that needed constent reboot) anyways they sold me a ACTIONTEC-GT784WNV - Looks very basic..

 I have a security camera system set up with port forwarding etc..  That someone help me set up.    The "Tech" told me I would not have to have to reset everyhting all up.. JUST switch routers and all port forward settings etc.. wil carry to this new router..

I'm a little nervous to do this.. and have everything go down.. with a xmass pkgs in the mail.. Is this a true statement can anyone confirm??, or will I have to re-do all my setups port forwrding etc.. on this new router.
