hello

I have recently change my company name from BHANU DIAM to  BHANUMATI IMPEX in same GSTIN registration number 

While i have update the company name in profile name that change all my historic data like sale invoices and purchase bill , i would like to remain historical transaction (up to the date of the name change ) remain in old name BHANU DIAM and new transactions under BHANUMATI IMPEX.

     Please guide me on how to configure this so that my past data remains unchanged while the new name applies moving forward...
