BI4.1 SP4 Upgrade Path

Hi

We are currently on BI 4.1 SP2 version and intend to move onto the BI4.1 SP4 Patch 2 upgrade.

Our installation path to BI4.1 SP2 is

BI 4.0 SP4 - - >  BI 4.0SP6 Update - -> BI4.0 SP6 Patch 3 update - -> BI4.1 SP2 Update [Screenshot attached]

What should be our upgrade path to BI 4.1 SP4 and how do we go about it.

Thanks!

Samir
