case status date update on ceac

After changing the employer due to previous 221g, I got 221g green slip again to withdraw the previous petition as per VO. I was told to dropbox the previous petition with passport. I did that on 6th Feb, after 2 weeks the case status date changed to 21st feb.

As the passport is with the consulate the status of PP is “there is no status update available on submitted PP”

Is the date change on CEAC a good sign ? Is my visa getting approved? Please advice
