What’s behind the move to HANA Cloud?
SAP has begun migrating the first SAP Analytics Cloud (SAC) systems from HANA 2.0 to HANA Cloud. While this process currently affects only a few customers, one thing is clear: the transition is coming – for everyone. By the end of 2025, a large portion of tenants will be migrated. At the moment, the migration process takes about a week per customer. However, by the end of the year, SAP aims to automate and optimize the process so that only a short downtime will be required per tenant.
Anyone who doesn't want to wait for the SAP- managed migration can also carry out the process manually in advance. But is it really worth it?
This article takes a closer look at the switch to HANA Cloud: what it means, what the benefits are, what to consider with manual migration- and whether the effort pays off.
The migration is part of SAP’s strategic evolution of the SAC infrastructure. The goal is to bring all customers onto a modern, future-proof platform: SAP HANA Cloud. This offers not only technical advantages but is also a prerequisite for new features – above all, Seamless Planning. This was released to selected customers in late 2024 and will be available in 2025 for all tenants already running on HANA Cloud.
The focus on HANA Cloud makes sense – SAP Datasphere is also based on the same technology. Seamless Planning leverages this common foundation, allowing SAC and Datasphere to be combined in powerful new ways, moving beyond the limitations of traditional SAC Planning. We’ve covered Seamless Planning in detail in a separate blog post.
Not least, HANA Cloud also enables new connection types, like the live connection to Google BigQuery.
The migration process started in mid-2025. Further details about the process and timeline are discussed and regularly updated in the community blog post. The migration is tenant-based and handled by SAP. If that’s too late for you – or if you want earlier access to Seamless Planning – you can request a manual migration via your SAP/SAC contact or SAP Support. SAP will then provide a new SAC tenant based on HANA Cloud. The old tenant will be decommissioned after 30 days, although extensions are usually negotiable. In this case, however, you are fully responsible for the migration.
And that’s where things get tricky – especially if your system still contains legacy baggage.
Short answer: In only a few cases.
Seamless Planning is undeniably a powerful step forward. Compared to traditional SAC Planning, it’s more flexible, more integrated, and opens up exciting use cases – particularly in combination with Datasphere.
That said, the feature set of Seamless Planning is still limited. Major updates are expected at the end of 2025 and early 2026 – right when most customers will already be migrated by SAP. So if you manually migrate now, you’re unlikely to see full benefits for several more months.
Early migration to HANA Cloud does offer some perks – like access to Google Live Query and a chance to clean up your system, remove outdated content, and revise classic stories.
But you have to weigh that against the effort involved. When SAP handles the migration, classic features like Legacy Stories and Applications are still supported until 2026 – meaning no major action is required on your part, aside from coordinating with SAP and informing SAC users about the scheduled downtime.
A new HANA Cloud tenant starts out empty – and all content from the old tenant must be migrated. But there are a few caveats:
In classic story tables, the “Optimized Presentation” option is often not activated
which is essential for a successful migration.
There are several technical limitations:
On the plus side: Export versioning is now possible, so you don’t need to create a brand-new export every time – this saves time and improves clarity.
If a manual migration is required – for example, for a sandbox tenant – follow these steps:
Another use case for manual migration is switching to a Private Cloud setup. The process is largely the same – but without the 30-day deadline. If you’re willing to pay for both tenants during the transition, you can take more time with the migration.
If you want to explore Seamless Planning now, consider migrating a separate sandbox tenant – ideally with “Fast Track” enabled. This way, you get updates every two weeks (instead of quarterly), allowing you to test new features earlier. Bugs may appear more often, but that’s usually not a problem in a sandbox environment.

For production systems, we recommend letting SAP handle the migration. They take care of the technical side and automatically transfer all supported content.
Regardless of your migration timeline, SAP (and we) strongly recommend switching to the new story type and gradually phasing out classic stories, applications, and boardrooms.
Seamless Planning is a promising innovation with lots of potential. But: The migration to HANA Cloud shouldn’t be rushed. Manual migration takes time – and the benefits may not be fully realized until later in 2025 or 2026.
The smarter approach? Let SAP handle the migration – and test Seamless Planning today in a fast-track sandbox. That way, you stay ahead of the curve without putting your productive system at risk.
