When did Syria stop using the MiG-19?

[Gunfreak]

A simple question, but google doesn't want to answer..
I find that both Iran and Iraq used it for ground attack in the 80s, I find that most of Syrias MiG19s got destroyed on the ground in war with Isreal, but finding out when Syria stopped using them, that I can't find,

From what I just read (Arab Mig-19 and Mig-21 Units in Combat), Syria retired their surviving Mig-19's after the Six-Day War, sending what was left to Egypt.
