STP advice on Groww App

Greetings,

I have around 10 lakh INR sitting in the Mirae Asset ELSS fund, for which I have stopped SIPs. I want to do an STP of this amount to either the Quant or SBI small-cap fund. However, the Groww app seems to only allow SWP in same AMC house . What would be the best course of action? If i redeem the whole amount , what tax implications i should take care of.
