ORA-01665 : control file is not a standby control file

Question

I've already tested Dataguard configuration on Oracle 10g Enterprise edition for Windows.
While configuring the same in Sun Solaris, I'm receiving this error:
ORA-01665: control file is not a standby control file
Steps I follow are as below:
1) Creating a password file on both databases (primary and standby)
2) Force logging primary db and shut it down. Take a cold backup of redo log files and datafiles.
3) Transferring them to Standby db.
4) Starting primary db in mount mode and creating a standby controlfile. Transferring standby controlfile to proper location defined in standby init file.
5) Start primary db in read-write mode and secondary db in mount mode using:
alter database mount standby database;
I receive this error while firing this SQL.
Can anyone please help me out solving the same.
