Loss carryforward and set off under new tax regime?

I have been filing under old tax regime until now - 

Somewhere on internet I read that if you have migrate to new tax regime 

all tax losses you have carried forward until now (under old tax regime)  can not be set off against profits (under new tax regime) bascially all losses I have to foget - it can not be set off or carried forward 

Please advise if this true?
