Sorry if this has already been addressed but I've just spent the last hour looking for the answer here.
Below is the list of products under the Sonar Platinum heading on the product download page. (I wanted to insert a screenshot but I don't know how!) I only bought and installed X3 in December so which of these must I re-install/update/download now that I have bought Platinum?
Thanks for any help.

Engineering FX Suite
Studio Instruments Suite

I had the same question as you Percepto.....
 
I went ahead and installed everything in Command Center as I didn't want to miss out on any updates (when available)......since everything goes through the CC.

Everything ...

But dont bother with Dimension or rapture, you probably have those installed already with X3. TBH I dumped dimension - not using it, old and not updated much.
 
Maybe remove Additive Drums 1 that came with X3 producer and then install Additive Drums 2 instead. You could do this via the XLN Online installer in the XLN Folder in the Windows / All programs Menu.



 
Keep in mind - I think installing via CC defaults to the program files folder. I couldnt find any way of changing this via CC settings. If you want to install Sonar Platinum into another folder then go via downloading from your cakewalk account online, then install each item to the location of your choice ( in my case it was my D Drive ).
 

Thanks for the replies but I'm still confused!
It can't be that all the samples have to be re-installed, can it? Do I have to remove the old ones? I just don't want samples or data clogging up any of my drives when I will never need them again.
Thanks again in advance for any input.

Perhaps if someone from Cake could chime in and give us a list of what gets installed from each sub-selection in Command Center it would help us to determine what we need to select for installation and not install duplicate things we may have installed from previous versions of Sonar.

This page (scroll down) lists everything that comes with each version, divided into sections. The new items are marked "New".
 
If in doubt just install the content (not Sonar) in the same place you installed last time, that way you won't have two versions loaded.  You should use one common set of folders for VSTs and samples as good practise anyway.

Still no clear answer and no bakers helping out?
Surely this is not a difficult question to answer.
I don't think it is too much to expect clear and precise instructions and I don't seem to be the only one with this issue.
I actually expected to be flamed for asking a question that has already been answered!
Help, please...

My post above yours answers your question exactly.  The page I linked to lists the contents of each of the sections in the downloads.  Scroll to the bottom of the page.

Install the content in the same place as you did for previous versions and you'll not have duplicates.

I installed platinum, then AD2. My X3 had AD1 and that is still there .That is it.
If an X3 synth or FX is missing, add the path to the VST manager.
I was missing one thing, it may have been Melodyne.
