Upgrade from ECC EHP3 to ECC EHP4

[Former Member]

Hi,

We are planning on a mini upgrade to the EHP4 patch. We are currently on EHP3. Is there a risk factor as in any upgrade ? I am just a little confused as they are only enhancement packs and their impacts on the functionality and lot of technical work that we have been doing.

Hi,

YES ! And contrary to what SAP says, I strongly advise to do some non regression testing even for non activated business functions.

Beware also of the Ehpinst runtime, it canbe very long and specially on the production system with the production load.

We just did a successful upgrade from ECC6 EHP 0 to ECC6 EHP 4 on the production system this weekend.

We estimated the cost, time and complexity of the project to be half of a full release upgrade. This was quite a bad surprise for the management..

Hi Teresa,

As you must be knowing that Enhancement Packages bring in new functionalities too apart from just support packages. All the EHP's uptill EHP3 are cummulative. EHP4 contains EHP3 and EHP4.

For more info and known issues i would recommend you to refer the following SAP Note:

1143022 - Installation of SAP Enhancement Package 4 on SAP ERP 6.0
