In-place Upgrade to AX2012 R3 - Remove non-DB components

HI There,

Can anybody help me to understand to remove non-database components from below technet article

technet.microsoft.com/…/jj733502.aspx

I am upgrading from AX2012 Feature pack to R3, removing non-db components includes AOS removals as well.

i can see following compnents from control panel

Microsoft Dynamics AX 2012 Client and Office Addins

Microsoft Dynamics AX 2012 components

Microsoft Dynamics AX 2012 Object server

Microsoft Dynamics AX 2012 Setup files

Microsoft Dynamics AX 2012 Trace Parser

Which are all to be removed?

Thank you.

Regards,

Rahul
