Database Migration using ASM

Question

Hello All,
We are using oracle database 10g on AIX. We are using asm for storage on a shared location.
Now we want to move our database from old servers to new servers.
I want to know if we could use the same asm based datafiles for new database to avoide database data migration. Can we switch our database from one server to another and use the same datafiles??? or we have to migrate our database by RMAN or expdp etc???

Answer 1

we want to move 9 Tb database from tru64 and filesystem to solaris and asm on 10.2.0.3, we will be testing RMAN with CONVERT;

and physical dataguard options.
so do you have any experience with the source and the target OS different case, like source as Tru64 and destination as Solaris;
SQL> SELECT a.platform_name, a.endian_format
  2    FROM v$transportable_platform a
  3   WHERE a.platform_id IN (2, 5)
  4  ;
PLATFORM_NAME                                                                    ENDIAN_FORMAT
Solaris[tm] OE (64-bit)                                                          Big
HP Tru64 UNIX                                                                    Littleor is there any similar step by step reference like Howard's article for same OS case?
Thank you, best regards.
