Upgrading SCCM 2012

We are upgrading SCCM RTM to SCCM 2012 R2.
Our first requirement is to upgrade to SCCM 2012 SP1.

My team leader wants me to install CU5  before installing R2.

If I do that do I also then need to install CU5 again after the R2 upgrade?

Here are two links about upgrading paths for SCCM 2012 R2 SP1
(Probably you have seen this 1000 times)

From:  http://blogs.technet.com/b/configmgrteam/archive/2015/05/06/now-available-cumulative-update-5-for-system-center-2012-r2-configuration-manager.aspx
"The fixes in Cumulative Update 5 for System Center 2012 R2 Configuration Manager are also contained in System Center 2012 R2 Configuration Manager Service Pack 1."

So you won't need to reapply CU5.

In the last link is also mentioned upgrade issue, that can be solved with install of CU5 prior to final upgrade.

Thanks Davorin, however the upgrade we want isn't R2 SP1, just R2.

Let me rephrase it:
Following the upgrade to R2, do we need to install R2 CU5 if we already installed SP1 CU5 prior?

We have no intention of installing R2 SP1 at this stage, hence my question regarding the installation of R2 CU5 following the R2 upgrade.

Thanks anyway.

If you're upgrading to R2, then I guess your boss will be happiest if you get to the latest revision by following this upgrade path:

R2 > SP1 > CU2

CU2 is just out but has a few key things in, especially cloud related, but still has plenty of fixes for non-cloud companies.

Useful information however we HAVE to go to SP1 CU 5 first.
I will assume that following R2 installation following that, that CU5 is not required as per your reply.
