Do successfull completion of all PREPARE modules require for running SPUM4?

Hello,

We are planning to do CU&UC for upgrading from 4.6c to ECC 6 and also converting it to Unicode.

It is on Oracle 9i.

We are going to do HW migration including OS and DB migration (to Oracle 10g) as well, this would happen just before golie weekend.

We want to do pre-conversion activity SPUM4 before DB upgrading to Oracle 10g.

Hence PREPARE module for checking DB version will fail.

The question, Is it possible to do Pre-conversion activity using SPUM4 few days before successfully completing all PREPARE phases (upgrading db to Oracle 10g).

Thanks,

Piyush
