Status of MiG-29SMT & Su-27UBM/30KN

Hi all,
does someone know something about the status of the MiG-29SMT and Su-27UBM/30KN aircraft for the RuAF?

AFAIK the first “production” MiG-29SMT was presented already in january 1999. I read somewhere the MiG-29SMT entered service with the RuAF in 2002. Is that true and if yes how many aircraft were upgraded to that standard.

For Su-27UBM and Su-30KN one prototype of each aircraft existed and AFAIK the RuAF gave an order for upgrading 30 Su-27UB, including the remaining 4 Su-30 aircraft in 2001. Some sources say now this order was cancelled in preference of the Su-27SM. What about that?

thx in advance
