Transfer of suit from regular court to commercial division court

I had filed a suit in May, 2015 in Bombay High Court, Original side, when commercial courts act had not come. Mine is a commercial dispute matter but since the court fees was not paid and only paid in January, 2020 hence the suit got registered but as a regular suit in October, 2021. My advocate is unable to convert (does not know the procedure to convert regular suit to commercial suit) it to commercial suit. Please if your learned can advise I shall be highly obliged.
