YouTube does not support direct subscription transfer, but with Google Takeout and a careful third-party tool, you can migrate your list in under 10 minutes. If you value security above all else, set aside an hour and do it manually.
The short answer is . YouTube does not offer a built-in "Transfer Subscriptions" button.
If you’ve ever tried to switch between YouTube accounts—or migrate from an old Google account to a new one—you’ve probably asked the same question: Can I just transfer all my subscriptions in one click?
Until YouTube builds this feature natively (don’t hold your breath), these are your best options.
The longer answer is more hopeful: while it isn't automatic, you can move your subscriptions without manually re-subscribing to 200+ channels one by one. Here’s how. YouTube subscriptions are tied directly to a specific Google account. From YouTube’s perspective, your subscriptions are personal data under that account’s privacy framework. Allowing a bulk transfer between unrelated accounts would raise security and spam concerns (e.g., stealing a user’s subscription list without permission).
