Urgrent - Moving instances across machines - Help

Hi

I have to move an oracle instance across machines. Following are the steps I have done.
1. I created a database instance on sun-solaris. The datafiles were placed in a directory /export/02/data. The oracle version installed on the sun is 7.3.2.1.
2. I took a tar backup of the data directory and moved it to a another server ( HP-UX )
3. I exploded the tar file under /export/02 on the new server. I copied the respective

   init(ORACLE_SID).ora and the config(ORACLE_SID).ora from the sun box to HP-UX
  box under the $ORACLE_HOME/dbs directory. 4. I set the env variable ORACLE_SID to the same instance id as the solaris one.
5. On starting the instance using the svrmgrl ( The oracle instance on the HP-UX ) is

    7.3.3, i got the error :
    ora-00205 - Error in identifying the control file.The control file names are there and the file permisions are OK. I do not understand this ? 6. I commented those control files which were not being identified and restarted the instance. Now i get the error message : ora - 00201 : Control file version incompatible with oracle version.

I have 3 control files , 2 of them came with the error, unable to identify Received on Wed Oct 01 1997 - 00:00:00 CDT
