You can apply it directly to 9.0. The IF’s are cumulative and therefore contain all the fixes in the IF’s that preceded it. If however you have a custom hotfix installed you will want to make sure the fixes in you custom hotfix are included in the latest IF otherwise you will need an updated hotfix as well.

Subject: Please, apply directly.

These fixes are cumulative.
