SAP EP Eterogeneous System Copy

Hi experts,

we have a productive SAP EP 6.0 SP17 based on two host Windows 2003EE (one for stand-alone database and other for EP+TREX) and SQL-Server database.

We would like to switch database to Oracle and so we have to perform a SAP-HSC; by reeding the documentation it seems possible with no special restrictions.

By your "infinite" experience is it possible to perform safetly it ?

And which are the main critical points and prerequisite that we have to take into account ?

Many thanks for your help.
