Forming and LLC, start new books??

I'm probably a little late in asking this question but...... I filed papers to organize as a Limited Liability Company and changed the name of the company at the same time. The papers are back from the state, I have my new FEIN, filed for a new sales tax number, new withholding and UC accounts. Today I had my bank accounts change (i.e. opened new accounts) and all of my vendor accounts reflect the new name. As it stands now, I am still basically the same company. I have the same customers, vendors, employees, etc. Can I/should I continue using the same set of accounting books? I use Quickbooks, and I'm wondering if there would be any benefit to closing out the old company file and starting a new one with balances carried over from the old file??
