Applying support packs in SAP netweaver 2004s

Hi,

I am working on SAP netweaver 2004s and currently our systems are on Support pack 9.

We want to move to SP12.

Can I directly apply SP12 or I have to apply SP10, 11 & than SP12.

SAP has recommended to apply patches after 2 april 2007 using Solution Manager optimizer.

Solution Manager optimizer can only be used for ABAP stack and for Java stack i need to used JSPM correct me if I am wrong.

Regards,

Manish
