Recently, I had created a new gmail account with cool id. So I wanted to transfer all my data to new account from old one.I was able to transfer files,passwords,bookmarks and other things. But I couldn't find a way to transfer my subscribed channels. And hence decided to use my programming skills to solve the problem.

• The first thing you need to do is to go to your old Youtube account and download subscribers xml file. See Here
• Convert xml file into json online. Here

• Import that json file in python and extract channel ids from it.
• Create new file and add links to all channel in it. for example https:/ /youtube/channel/CHANNEL_ID

• Login into google account using selenium
• Go through each link stored in file from step-2;
• Click subscribe button with selenium
