Oracle Database Discussions

I have a database flash_recovery_area structure from a Windows host with Oracle 10g. Now i want to restore a given date backup to a Linux host with Oracle 11g.
Important: I DONT have access to the original Windows host, just to the backup files and my Linux host.

I am an oracle newbbie, and so i have a couple of doubts about thing i've read somewhere on the web.

1) It is possible to do that? I mean, restore a Windows oracle db to a Linux host? I read somewhere about incompatible bigendian, little endian, etc.

2) I ve tried the restore operation following instructions from diverse sources on the net, and i reach the point where the controlfile is restored, but i cant rename the datafiles (located under c:\Oracle\ ..... on the original host as i can see when i do select * from v$datafile;), cause when i try to do

ALTER DATABASE RENAME FILE 1 TO '/u01/ ..... /system01.dbf'

oracle says cant locate 'c:\Oracle\ ... \system01.dbf'

Please, i need help!!
