Let's be honest - upgrading a SAP Commerce (Hybris) platform is a task that nobody loves. Often you start the project under pressure, forced by expiring version support. And since real business benefits through the upgrade are hard to achieve, it's hard to find a budget.
Unfortunately, there are no reasonable ways around it, so all you can do is to focus on getting the job done smoothly and quickly.
In this article, we will discuss the prerequisites of a successful SAP Commerce (Hybris) version upgrade with the least amount of effort and risk for the organization using proper strategy, planning and efficiency of execution. From our text, you will learn that:SAP Commerce upgrade is a project with unique characteristics
- It may bring your business great value if planned properly
- Respective software versions have caveats significantly affecting risk and effort
- Thorough analysis and quality assurance is key to eventual success
- Skilled and experienced teams are of immense help
What is an SAP Hybris upgrade? We talk about an upgrade project when a commerce project built on top of SAP Commerce is expected to use a higher version of its core component - the platform. Based on our experience, customers rarely engage in upgrades and prefer to maintain the proven old core of their system for as long as possible. Thus, from a system maintenance perspective, the upgrade can be considered a typical but rather infrequent hygienic activity.
New version may bring value to the business New features released by SAP are always described in release notes and the documentation. But customers are rarely following those sources and thus can’t benefit from new functionality. Some improvements affect areas which may help business right away, or with just a slight degree of integration effort. Checking all new versions for potential value for the business is a proactive approach which helps in finding budgets for the task.
Still, the main driver for starting an upgrade project are:
- Security concerns related to deprecated technologies
- Company policies dictating the use of particular stable software versions
- Expiring vendor support
Include upgrades in your long-term road map While SAP clearly communicates the benefits of new versions, they are also relatively clear about their support periods. It's no secret when a respective version’s support expires, and this is a piece of essential information when maintaining a SAP Commerce - based software platform. You don't want your upgrade task to pop up on your priority list at the last minute before the support expiry. Notably, since upgrades bear a highly varying level of complexity. What if you end up embarking on a fewcmonths-long project just to regain vendor support?
Now, frankly, this scenario has not occurred very frequently in the past - SAP proved to be somewhat lenient when it came to extending the support period. However, and that's extremely important to note, recently we have been observing a significant change in SAP's attitude. The dates are considered more and more final, accelerated mainly by the strong push to the cloud.
Thinking of upgrades in advance, analyzing the impact and including it in your overall project mitigates the risk of running into unpleasant surprises as far as the scope of the project upgrade is concerned.
Plan an upgrade like a regular delivery project Upgrading a SAP Commerce engine for a complex commerce platform doesn't sound like a simple task. It is a real project, and it should be structured as such. It requires careful planning, a skilled team, flawless execution and reliable quality assurance.
However, the upgrade project has its unique characteristics that you should account for. Firstly, it seems to fit perfectly into agile delivery models, as initially there is a much higher level of uncertainty which only gradually clears up as the project progresses. Secondly, attention needs to be given to synchronizing the upgrade work with potential functional development, possibly performed by other teams. Often those activities are performed in parallel and affect the same codebase and infrastructure.
Be aware of the caveats in your go-to version When it comes to the complexity of an upgrade, it depends mainly on the respective versions to be skipped or reached. The total effort spans from a few days to likely more than a hundred.
Often, exchanging the platform is a relatively straightforward task, which can be handled efficiently provided sufficient testing. On other occasions, it ends up being a real hassle. Imagine your system relies heavily on the old promotions engine which has been disabled in 1905 and likely will be removed in a future version. It effectively means you will need to reconfigure all your promotions and re-implement the extensions.
Or what if most of your backend processes are based on the old hmc and cockpits? As we all know, it has been destined for end-of-life for years, but SAP had not pulled the plug for a long time. After they finally did, many customers found themselves forced to quickly configure and customize replacements, during their next upgrade to version 1811 or above. Changes may be so far-flung, that they introduce new business processes and users have to adapt to new ways of working which requires new training. That's a big impact for a simple core library upgrade!
Extend the life of legacy back office As we have touched on this topic, at ENGINIETY, we have developed a solution which would allow you to extend the life of old backend applications despite the necessity of migrating to 1811. If you face the challenge of this particular upgrade and want to stick with your proven back office (hmc/cockpits) for some more time, we would be happy to help you achieve this.
Assure quality on multiple levels At the end of the day, an upgrade can be considered successful if the project ran on time and on budget, and ideally generated some additional business value. Not insignificantly important is the fact that the system does what it did before, without any flaws. It needs to be assured that the entire scope of functionality is not affected by the version change.
There are various ways of achieving this goal. We always strongly advocate creating and maintaining a broad suite of automated tests. Apart from improving the overall quality and productivity, those are of unparalleled assistance to ensure a successful upgrade. If not available, manual tests have to cover for their lack, but make sure those are based on sufficient and well-managed test plans. A "smoke test" approach is risky as upgrades may cause issues on the edges and corners of a system, usually not covered by any smoke test.
Make best use of test environments A crucial aspect to consider is the final deployment to the production infrastructure. As expected, the implementation of a platform upgrade is more likely to fail than a regular one. This happens due to the extent of the changes. It must be thus tested on systems which are analogous to production both in terms of infrastructure and data, usually called "acceptance" or "pre-prod". Preparing for upgrade deployment makes for an excellent opportunity to review those systems’ configurations and disaster recovery procedures so that they ideally match production.
