Will SagePay modulel conflict with previously installed HSBC module?

[sup_dude]

Hi,

 

I have set up an Oscommerce online store with the HSBC payment module. I have also added other modules including STS, various security modules, a shipping module, etc.

 

I don't want to have to start with a fresh install, but my client is changing his merchant bank account to Lloyds TSB. I was told by Lloyds TSB that unlike HSBC, they require a third-party PSP such as SagePay.

 

I am concerned that when I installed the HSBC module, following the instructions carefully, I had to add,remove and replace several line code.

Will I be able to simply install the SagePay module in my already modified OsCommerce or will there be conflicts?

 

Any help would be greatly appreciated.

 

Many thanks,

 

Darren
