Hello All,
We have Ecc6 with Stack 11 single stack (i.e Basis at 13 , ABAP at 13 , APPL at 11).
We have upgraded our solman to Ehp1 and the maitenance optimizer is configured properly.
I know that we have to use the Mopz for dowloading the Ehp4.
I have the following queries.
1.) Should we first upgrade the SP stack of the ECC6 from 11 to 15 (i.e., one level below Ehps packages) using SPAM and then install the Ehp4 package. with ehp installer. In other words is there any pre-reqisite support that the Ecc has to be before starting the Ehp4.
OR
Directly start the installation of the EHp4 with ehp installer and it will also do the stack update.
2.) How can we calculate the downtime required.
3.) If the Ehp4 is similar as sapup(upgrade) so there will be some downtime -minimized option. So in this case what will be the total downtime (i.e apprx how much time in hrs)
Regards
Anthony
