Can EhP4 to EhP5 be Cnsidered an Upgrade

Can EhP4 to EhP5 be Cnsidered an Upgrade?


If you only apply EhP5 without any support packages, it's not considered an upgrade. The EhP5 pack does not touch any of the existing objects in your system, it will only add new functionality. However, it's highly recommended (and often mandatory) to include the latest support package stack whilst applying EhP5, and when you apply support package stacks, you must always perform a full regression test in your system.
Another concept-:SAP's marketing strategy is to say that Enhancement package Stacks is not an upgrade, but in reality it is the same amount of work as an upgrade.
You really need to use the Solution Manager Maintenance Optimizer to extract the full Stack packages and apply to the DEV system then you project team need to perform full Regression Testing.

terminated.
Ans-:
Q when I'm trying to use the SNC Web UI, the Internet Explorer is unable to display the page.
ans-: This looks like it is the log of an installation; is that correct ? Either way, I would look at:

* the system prerequisites,
* the amount of SWAP space (or paging file on Windows),
* and the Java parameters.

it's the log of an installation.
