You can omit step 2, the Unicode conversion is an export/import method.

So

1. Prepare and export your non-unicode system

2. Build new system with the export

(3. Upgrade to CRM 5.2)

The exports themselves are bitness independent so you can import them into your target system.

Just use the normal Unicode conversion guide to prepare and export the system, then use that export to build up the new system.

Hello Markus,

Thanks for your quick response!!!!

I understood - what you have mentioned for my question but i have one clarification on your answer and one new questions to you.

........................................................................................................

Clarification:

My oldsystem is non-unicode system. As you said i will do system copy export method on old system(non-unicode) then i will use that exports(non-unicode) to build new system.

Here my clarification is:

Will that exports(non-unicode) work while installing new system with unicode? or Will it give any problem?

.......................................................................................................

Question:

1. will old system with oracle 9i exports work on new system with oracle 10g?

Thanks Advance,

You understood me wrong.

The Unicode migration is done using Export/Import (see the conversion guide). You prepare your old system, export it and import it as UNICODE in the new server.
