克隆数据库从windows到linux的土办法

是不是有种可能，从windows克隆到linux上？

Source database in Windows - DBName - ORCL (11.2.0.1)
Cloned database in Linux - DBName - ORCL (11.2.0.3)

Step 1 :- 从windows上创建参数文件
create pfile='/home/oracle/p.ora' from spfile

Step 2 :- 关闭windows上库后启动到mount
shut immediate
startup mount

Step 3 :- 执行冷备
rman target /
backup database format 'D:\BAK\full_%U';
backup current controlfile format 'd:\bak\control_%U';

Step 4 :- 将备份片拷贝到linux（这以后就与windows无关了）

Step 5 :- linux上启动到nomount（注意修改参数）
startup nomount pfile='/home/oracle/p.ora';

Step 6 :- 恢复控制文件
restore controlfile from '/bak/CONTROL_A7R4O1B4_1_1';
sql 'alter database mount';

Step 7 :- 校验过期备份
crosscheck backup;
delete expired backup;

Step 8 :- 在linux上注册备份
catalog backuppiece '/bak';

Step 9 :- 恢复文件到新位置
run {
set newname for database to '/u01/oradata/ORCL/datafile_%U';
restore database;
}
switch database to copy;
alter database open resetlogs upgrade; --如果同版本不需要upgrade

Step 10 :- 执行其他升级脚本
