Poland updated their S-200's in 2000... Also, the US is/was working to provide Ukraine with a FrankenSam system based on Patriot missiles using Ukrainian radars. Ukraine has plenty of S-300 systems but no more missiles. With this system, they could place a Patriot launcher near the front without risking a full Patriot battery.

American defense officials and engineers are also still testing what may be the most powerful FrankenSAM yet: a Patriot missile and launching station that operates with Ukraine’s older, domestically made radar systems.A Pentagon official said on Wednesday that a test flight of the system this month, conducted at the White Sands Missile Range in New Mexico, successfully hit the drone it had targeted. The system is scheduled to be sent to Ukraine this winter, the official said, accompanied by donated missiles and other Patriot parts from multiple allies.
That would be a great upgrade
