Alignment of customizing after upgrade

Dear all,

I upgraded a CRM 4.0 system to CRM 7.0 EHP1

Now the developers / functional experts complain that the customizing is not complete in client 030

I told them that the new customizing entries are only available in client 000 after the upgrade and that these entries should be 'merged' in the client 030 by means of transaction SCU0

Days are passing and more and more customizing problems arise and I'm asked to find another way of aligning the customizing between client 000 and client 030

Do any of you know another way then SCU0 to do this?

CRM devs/functional want me to redo the upgrade transports specifying the client 030 as target but this seems completely unreasonable to me ...

Regards,

Sebastien
