ASP.NET MVC4 to ASP.NET Core 8

Question: 

Should replace our DevExpress controls with supported .NET 8 controls?

What are our options going forward?

Background

We are migrating ASP.NET 4 MVC to ASP.NET Core 8. Our application has DevExpress controls which underneath uses System.Web(.NET Framework 4.8). DevExpress controls use System.Web assembly or extend System.Web.UI.Control from that library. Regarding documentation ASP.NET Core 8 doesn't support System.Web.UI.Controls. And our code doesn't compile because of that.
