  • Business challenge: Lower the maintenance cost and risk
  • Our solution: Moving to second-generation cloud
  • Project length: 122 Days (on time as estimated)

By simply migrating to the second-generation of the Oracle Cloud, Gränges is now ready for the future.

Gränges, located in Sweden, is a global leader in aluminium engineering, manufacturing and innovation. While the company is still looking into how to make the most of this opportunity on second-generation cloud, it has already noticed improved performance in line with lower costs.

Second-generation cloud provides increase value by running the same workloads with better features, faster speed and at a lower cost. To minimize both risk and cost, Oracle Consulting decided to complete a 1:1 migration. This included keeping the same architecture, shapes and sizing, without adding any new services. Additional services can be handled under the ordinary lifecycle management after migration.

We decided to use E-Business Suite Cloud Manager to do the work for us, which in simpler terms means: it takes a backup, transfers the backup to the new region, restores the backup and leaves us only with some minor configuration changes.

We began with migrating a test environment, which gave both us and the customer confidence, documentation of the necessary steps, and a strong insight into how long it would take – all essential factors that we were able to collect while business was running as usual.

Our end-to-end approach offered Gränges a flexible, secure, and scalable path to the cloud.

"Moving to Oracle OCI gave a noticeable improvement in performance in our ERP system. We also greatly appreciate the possibility to easily scale the application when special needs arise while maintaining full control of the costs.”

- Öystein Larsen, IT Architect from Gränges Sweden

After migrating our test environment, we migrated the production environment as a test, which provided the specific amount of time needed to transfer the production environment, and indicated that we had fulfilled all requirements on a basic infrastructure.

Following this successful execution, we felt confident enough to ask for a service window and began migrating.


3 tips for second-generation cloud migration

Below, I have summarized some of my thoughts on what to consider when looking at such a migration:

1. Decide how you want to migrate. Often you could do a 1:1 migration which means that you try to migrate as-is as much as possible. This approach will be both quicker and safer since you know what to expect, but you will miss some of the new goodies. However, this an acceptable tradeoff for less testing, and nothing prevents you from adding additional services later on. You want to minimize the risk and the cost as the first phase.

2. We strongly recommend you to use “Oracle E-Business Suite Cloud Manager”, which will help you with all the steps from start to finish, from migrating to actually managing the system.

3. A proper test plan gives you confidence in understanding how long the downtime will be. Besides getting an idea of how long you will need to transfer your data to the new region, you also get the confirmation that you know and have control over all steps, you know what and how to do it, and you have the confidence to ask your business for a service window to move the production environment, which will demand a downtime.
