I've been building a world on a private server for some time. However, neruxvace.net does not support version 1.15 of Minecraft, but there are new things that I want to use. In order not to lose my world, I wanted to transfer the world stored on the private server on neruxvace.net to a free server from Aternos. So how can I transfer the world from my private server to my PC or to the server on Aternos?
If it's not your server isn't at all. Possible to ask the server owner if he leaves the world to you and you can download it via FTP.
If he refuses this, you are unlucky.
What Synonymous said is true, it still is possible to get the world partially using the WDL Forge mod
