Moving VB from .ca to .com domain
 

What is the proper way of moving all content from a .ca domain to .com domain and then telling the bots to update the url's in search engine?

I installed VB on www.3djobs.ca and I want to change the domain to www.3djobs.com. What I currently did seems to work perfectly, or thats what I think. My domains are on the same server/host so all I did was point the 3djobs.com to the root folder and now when you go to www.3djobs.com all the urls contain 3djobs.com and not 3djobs.ca. Thats exactly what I want yes or is there more?

So now the other question is how will bots know to change their urls in the index? I think by having 2 domains point to the root creates 2 identical sites which is not what I want to do. I cant really do a 301 rederect on all the pages to rederect to .com because it would just create a loop cycle of rederects since now the .com is pointing to the root. But what I can do is point the 3djobs.ca to a folder like /3djobs.ca/ with a rederect index.html file? But then again that wont work because if someone clicks on a url from a google search result then the rederect will not take them directly to that full url instead it would take them to the 3djobs.com homepage.

Please help, this is first time I am doing this. Thanks.
