Hello
Technical implementation of ECC from 6.0 EhP3 to EhP7 with no new features being switched on.
Technical upgrade to Enterprise Portal 7.4. We are currently running version 7.0.1 Portal.
Technical upgrade of SAP PI and SLD from version 7.1 to 7.4
Technical Upgrade of SAP BW from 7.01 to 7.4
Please advise how much time frame and if possible explanation on the same
Consider a week's time for each upgrade activity. When I say a week's time, it is to upgrade one system in the landscape.
Eg: Upgrade the development system in the ECC landscape to EHP7.
So one week for each system in a landscape and also it is just a rough estimation for the duration of the upgrade. It can also take more than a week for upgrading a system.
Based on the target version details you need to first get the OS and DB upgrade if they are not on a supported version.
Check PAM for supported OS and DB information.
To know the upgrade procedure and activities involved you may read the upgrade guides.
