ESBC acme packet 1100 patching procedure

We've purchased three SBC Acme packet 1100. The devices have the rls 9.2.0p1 already installed from factory.

We would like to update them to the newest software before put them in production. Currently the last one is scz9.3.0 as we see on the Oracle support site.

As per the update indications on the documentation, prior to perform any minor/major update we must be sure that the source release (9.2.0) is updated with the most recent published updates.

We see the most recent update for release scz9.2.0 is p5.

As we are in scz9.2.0p1, we need to go to scz9.2.0p5. do you know if we have to install p2, p3, p4 and p5? or can we install directly p5?
