SAP Landscap

Dear All,

We have implimented our SAP before 4 years.

Our SAP Landscap is on HP-UX and database is oracle.

Our transport route DEV -> QAS ->PRD.

We are doing our testing on DEV system in which we are refreshing one client with production every 15 days.

We are not doing any think on QAS. It's just a transport route. In very rare case we are using QAS.

I have the following queries :

1. Is it advisable to remove QAS form landscap.

2/ Our SAP Landscap is on HP-UX and database is oracle. Is it advisable to put QAS on windows server. Becauase we required one HP Unix box for our testing purpose.

Regards,
