Transferring posts from FB to VK?

Question

Facebook

Hello, there are a huge number of posts in FB and they need to be transferred to the VK group while maintaining the order. Of course, I would not want to do it with my hands, but there are also photos, videos, text with links, and so on. I made a JSON upload of posts from FB, and then what?

In general, write whether this is a real task, if you take a long time to figure it out and give it to someone for outsourcing?
