You will find listed all the latest and best tools to help you on your journey.
You can even find advice on potentially tricky questions such as what to do about your SAP Fiori architecture if:
- You did not set up your SAP Fiori in your initial implementation of SAP S/4HANA
- You are already using SAP Fiori and considering whether to save on costs and simplify your architecture via transition from standalone to embedded mode with your upgrade
But wait there’s more!
SAP S/4HANA has progressed in leaps and bounds over the last 5 years. You have already seen out-of-the-box innovations come to SAP S/4HANA such as embedded analytics, chatbots, machine learning, SAP Intelligent Robotic Process Automation, and SAP Fiori Situation Handling.
You have already seen brand new (never provided in SAP Business Suite) processes such as Predictive MRP, Group Reporting, and Central Procurement.
You have seen more and more industry solutions covered, more languages supported, more add-ons embedded.
You have seen flexible business model innovation made achievable, where running multiple industry solutions side-by-side has moved from impossible (with SAP Business Suite) to easy (with SAP S/4HANA).

You can access additional learning content in the SAP Enterprise Support Value Map and watch out for some coming sessions in the SAP Enterprise Support Academy (Learning Hub – Enterprise Support Edition). Find out more in blog post Is it time for an SAP S/4HANA Upgrade? And is it really necessary?
We are willing to migrate to SAP S/4 HANA but SAP has not yet released the Industry Specific Solutions for Media which forces us to remain on SAP on HANA. What is surprising is SAP do not have a road map for Media Vertical. Approximately 232 Customers world wide is left high & dry with no migration option.
It is high time SAP takes care of their existing Customers across all Industry verticals while promoting the S/4 HANA version.
Hi Varkey,
Sorry to hear of your frustrations. It's true that the careful journey to include different IS-solutions has taken some time.
A small part of IS-Media is already covered and a side-car approach for IS-Media with SAP S/4HANA is also currently possible as explained in the most recent SAP Note 2677010 - SAP Media in ERP / ECC 6.X and SAP S/4HANA
By the way the SAP Roadmaps information for SAP S/4HANA has just been updated for June and can be found in the new Roadmaps Explorer tool - I see 209 innovations related to SAP S/4HANA + Media planned out from now to 2022 so perhaps at least some of your needs may be covered by then.
With regards to this particular guide blog post, I also wanted to make sure you were clear that this guide is about upgrading between SAP S/4HANA releases, and so it is not relevant to your current situation.
To move from ECC to SAP S/4HANA is termed system conversion, and you can find more information on that on the sap.com site for the SAP S/4HANA movement.
I hope that helps somewhat
Its a great blog and we see many customers going for S/4 upgrades now. I just want to add that SAP Solution Manager accelerates the upgrade process further with the following capabilities
Of course the traditional process management and change management capabilities can also be leverage if the customer is undergoing a bigger functional upgrade process with additional requirements and scenarios being implemented as part of the upgrade.
Thank you Rajeev .Useful info

Hi Jocelyn,
Very nice blog. Just wondering will it be the same approach for cloud STE & MTE for testing approach. Thank you

Hi Vyomakesh, We are only discussing SAP S/4HANA on-premise, SAP S/4HANA Single Tenant Edition and SAP S/4HANA Private Cloud Edition here.
i.e. SAP S/4HANA on-premise software on on-premise or on Cloud infrastructure.
SAP Innovation and optimization Pathfinder link is not working any more.
Thanks for noticing Samir - the pathfinder report is has now moved to Spotlight and can be accessed here
Hello,
Very helpful !!
Do you know the feedback of the quantity of custom code changes, Have you faced a lot of regression ?
Kind regards,
Hi Sebastien,
Generally speaking it's usually much less than customers think - for starters most database reads are automatically covered, so it is mostly database writes and mandatory ABAP changes that need to be corrected. The Eclipse ADT brings a lot of Quick Fix options that speed it up.
General experiences even at large customers with many programs are 2-3 developers focussed on this for 2-3 weeks.
One watchpoint is to think about the move from working directly on a GUI for Windows operating system to only via a web environment. In particular, anywhere you have an upload/download program, if you want to run that in the web you need to rework from OLE automation to GUI Frontend Services.
You'll find some more advice in this blog post: SAP Fiori for SAP S/4HANA – Transitioning custom-built programs from GUI to Fiori
Hi Sebastien,
it very much depends on the quantity of custom code / complexity of the extensions. Most customers are done with the code adaptations within 2 to 3 weeks with 2 developers, some even within a week.
Due to compatibility being ensured, it's also a possibility to focus on the most important fixes before go-live and fix remaining code subsequently after go-live. It will still have to be done to improve performance, etc., but wouldn't hinder a go-live before when not done at 100%. Again, it depends on the type of custom extensions and complexity.
Thanks and best regards,
Thomas
Hello, Thanks for reply.
Is it possible not to do the "required" custom code BEFORE the non-regression tests ?
What happens in this case ?
Kind regards
Hi Sebastien, I'm not quite sure if I have understood your question?
Where changes are required in custom code, usually the related program won't work until they are fixed. So there would be no point testing until the code was fixed.
Of course it might depend what processes your custom code impacts. You may be able to test processes that do not depend on that code.
Hi
What happens to user-developed custom Fiori if I upgrade my old S/4HANA to the new S/4HANA?
Can I continue to use the custom-developed Fiori as it is?
If a refurbishment is needed, what tool can I use to investigate the refurbishment?
regards,
Hiroshi
Hi Hiroshi
Generally speaking custom Fiori apps evolve nicely ... mostly with few changes in our experience provided the best practice recommendations from SAP were followed. You may have some changes if the app is very old, e.g. written on SAPUI5 1.38 or lower (i.e. SAP S/4HANA 1511). Anything written on S/4HANA 1609 or higher is already at Fiori 2.0 design level so tends to evolve.
Please take a look at the references in section 2.7.10 Required adaptations to custom SAP Fiori Apps. You should as due diligence check the upgrading advice in the SAPUI5 SDK https://ui5.sap.com for your source and target releases.
Regression testing is always recommended of course to make sure.
As a bonus, custom apps based on Fiori elements floorplans automatically pick up improvements from the floorplan.
By upgrade of S/4HANA instance, will there be any impact to the standard Fiori application that has been used?
Hi Hiroya,
Thanks for the questions! This is why the new Upgrade Impact Analysis tool has been introduced to help you work through these for the list of apps you are currently using and your source and target SAP S/4HANA release.
In summary, there are a number of possible impacts:

Hi Jocelyn,
In our SAP S/4HANA implement approach, we decided in 2019 to use SAP standard catalogs to provide Tiles to business user; without using any group : User have to setup his own Launchpad.
We have discovered on the last upgrade (2020 fps01) that every Tiles that have been changed by SAP in Fiori Catalogs "SAP*" are not running anymore.
User see the "Tile can not load" error on their UI Fiori Launchpad.
Tile can not load, due to change on SAP Catalogs
=> He can not even identify which are the missing apps "xxx" if does not remember well before upgrading.
Do you have any idea to avoid this ? We did not have found any clever solution to anticipate this impact for every users and clever solution to fix it.
Thanks
Regards
