Could somebody help me port a CSGO map to CS2?

[deny]

Hi!
Ive tried many tutorials online, checked the valvedeveloper site for more info however failed. I followed the steps but something was always off for some reason. This is the map and my main account that made the map (i cannot post on discussions with that account for some reason) https://steamcommunity.com/sharedfiles/filedetails/?id=643878438
Please, if somebody could help feel free to add me on my main acc. Cheers!
