Switching podcast to new website

Hello,

I am in the process of creating a new website for my podcast/business, Thought For Food. I have the original site (www.thoughtforfoodpodcast.com) where all 30 episodes are located. I have created a new site (www.tfflifestyle.com) where I have installed the Blubrry plugin and have successfully migrated over the podcast feed (I think, there’s a new feed associated with the site). My iTunes feed is located there now too, and have started the process of moving over the blog posts. I am continuing to post new episodes through the original website until I’m ready to launch the new site. Once the new site is good to go, can I stop posting from the old one and just go with the new one? Will I lose all of my subscribers? I just want to make sure I’m doing this properly and correctly. What other steps should I take to ensure that this is going to work? I appreciate any and all help, thank you guys so much!
