Authinfo-Code to move traffic from old site to Presta Shop

[schaumkrone]

I just now finnished to build my Presta Shop and have requested an Authinfo-Code with my old provider.

 

I do think i need to add this Authinfo-Code somewhere in the shop backoffice area in order to redirect all customers from old place to new place??!!!

 

I searched everywhere and can´t find it ---

Could somebody pls tell me what to do?

 

I would hate to loose clients.

 

Thanks in advance
