I've been using Django for quite a long time and in my opinion I would never switch from it. My company is currently using Django with REST framework and a part in GraphQL using Graphene. On the frontend we use Next.js and so far everything has been running quite good. I've found limitations but manage to solve it.
As someone mentioned before, if you are comfortable with Django, don't switch. There's no need since with django you can basically achieve anything. Of course this will depend on the project you want to build, but the scalability and flexibility django can offer it's just out of this world. (Don't want to sound like a fan boy haha but it really is).
It's been ages since I last used Django, but if you're proficient with it, I'd suggest you stick to it in order to deliver results quickly and on time. On the other hand, if time is not an issue, I'd recommend you start learning Node.js with express.js or loopback.js.
Bottom line: Start learning Node, keep using Django till you get proficient at Node, then move to Node ;)
I haven't found anything close to the Django admin in Node.
Keep in mind that comparing Node.js with Django is not quite right. It's like comparing Python with express.js
