Is it difficult to connect a server with golang sockets?

Question

go

There is a monolith, which is slightly fragmented into 3 servers, base, sockets and front + back.
The service is growing, a lot falls on the sockets because constant communication, the average online is 4-5k, only 30k people and it is growing.
After reading habra, there was a desire to build a socket server on golang.
In one of the articles on Habré, the issue of the census was raised, the most productive socket server was on the elixir, the second place was golong, kept online at 30k on a weak machine (core i5), there was a test on a home laptop.

Actually, the question is, now everything is connected with the laravel pusher, how difficult will it be to remove the pusher and connect the golang sockets? How much code will need to be shoveled and where to start where to look? There is no experience in golang, as well as a similar code rewrite.

On the old server, when testing the maximum load, our server gave out 7k online, which is 3 times less than the socket server on elixir / golang. Therefore, we asked this question.
