Upgrade EHP4 SP stack 06 to EHP5

Hi Dear,

We are on EHP4 SP stack 06 and would like to upgrade EHP5, Is that the same if we perform upgrade SP stack level 09 that is equivallent to EHP5 or we had to follow other path?

The reason why I have asked the above clarification, during our Solution Manager upgrade just we perform the SP stack 15 to 22 and it is equivallent to the EHP1 now.

Regards,
