32bit Primary to 64bit Standby-"ORA-00704: bootstrap process failure"

Question

Hello All,
As per the Doc ID 414043.1 it is possible to use mixed word size primary-standby configurations since 10g and better in 11g.
So i created my test env:-
OS: Linux 5.5 64bit
DB Name: TEST
Primary  - TEST32 on 32bit Oracle Home
Standby-  TEST64 on 64bit Oracle Home
I could apply TEST32's archive logs(manually) on TEST64 without any problem, but when i tried to migrate to 64bit it kept failed with "ORA-00704: bootstrap process failure ORA-39700: database must be opened with UPGRADE option"
What i did on TEST64 is:
1) Activate physical standby
2) Startup Upgrade
3)@?/rdbms/admin/utlirp.sql
4)@?/rdbms/admin/utlrp.sql
5)Shutdown
6)Startup
When i issue startup(step 6); it fails with
<pre>
SQL> startup;
ORACLE instance started.

ORA-39700: database must be opened with UPGRADE option

SQL> exit

Did i go wrong somewhere ?
TIA,
