That's the million dollar question right now. As per the BEC FAQ, the online system was supposed to switch status from TR to RIR once they got the conversion package and found it acceptable to be put in RIR queue. However, this happened only for some cases back in January. Since then, most RIR conversion cases are going straight from TR-In Process to TR-Certified instead of first going to RIR-In Process (and this too is happening only at DBEC, there is absolutely no information of any changes/certification of PBEC cases).
So, at this time we can only wait for the conclusion.
