Install update 6 on solaris with update 3

I want to update my solaris 10 server which is currently on update 3 stage.
A new application require it to be on update 6.

What is the best way to make it update 6.

should i just install the patch or should i go for the liveupgrade??

thanks for you help in advance

just patching won't take you to update 6... you'll need to upgrade.

anybody is having procedure documentation for upgrade?

take a backup (ufsdump or something like that), insert the DVD (or boot over network, whatever you use) and follow the instructions. after the upgrade use the latest patchcluster.
