Upload Minecraft 1.12 Map

[Bizario]

Hello!
I would like to upload a 1.12 minecraft Map (with the old command blocks versions). I Zip the map and upload it but when I go to the server the world is a "classic" one. Is it possible to upload functional 1.12 map (with the old commands) or they became obsolete ? Do you have any solution ? (I already install the Protocol to use the server in old versions)

Thx a lot ! Now I can go to the map! 

But now the problem is that the commands (in command blocks) are obsolete cause of the 1.15 minecraft version (my map is a 1.12) is there any plugin or setting on minehut plateform to set the old minecraft commands versions ?

Thx again for youranswer ! @Emily
