Thank you so much for all the responses. So it sounds like 301 redirect through htaccess is the way to go. What is the difference between using the 301 through htaccess vs using rel=canonical in my case? Does the 301 provide better link juice vs rel=canonical or is canonical just not applicable in this case? Thanks for all the replies and helpful suggestions again!
EDIT: I spoke to my developer (who is hosting and maintaining my site now).. he said he tried to do 301 through htaccess but it seems to be crashing the site (and trust me he is very good at what he does). Part of the problem is that my site is VERY old (originally build about 10 years ago and NOT updated once since).. he has been slowly updating and cleaning up the site slowly and he will try to figure out why the 301 is crashing the site and not working but in the mean time how safe is it to use rel=canonical instead of a 301?
Thanks again!
