Migration to Mainboard

Migration is the process by which an SME-listed company moves up to the mainboard of the NSE or BSE once it meets the larger exchange's criteria.

SME companies that grow and meet mainboard eligibility — including paid-up capital, profitability and public-shareholding thresholds — can migrate to the main exchange. Migration brings access to a wider investor base, index inclusion and greater liquidity, and removes the market-maker requirement.

The move requires shareholder and exchange approval and compliance with SEBI mainboard norms. Migration is often seen as a milestone signalling that an SME has matured into a fully-fledged listed company.
