Migration Process for OAS 2025
Version 2025
I have recently completed a fresh installation of OAS 2025 in a test environment. Now, I'm considering the best approach to migrate this setup to higher environments (e.g., staging, production). I have a few questions regarding this process:
- What is the recommended approach for migrating OAS 2025 to higher environments?
- I initially planned to perform a fresh installation and configuration in each environment. Is this the best practice?
- Are there alternative methods available, such as: a) A cloning process? b) Using VM snapshots?
- Could you provide any official documentation or guidelines on this migration process?
Thank you.

@sgeorge_otn - Welcome to the Oracle Analytics Community!
Thanks for reaching out. Please find the answers to your queries below:1. What is the recommended approach for migrating OAS 2025 to higher environments?
OAS 2025 is the latest available version as of now. The recommended approach for migrating between environments is by using snapshots. This method ensures consistency in moving content, configuration, and metadata across environments.
Refer to: Administering Oracle Analytics Server documentation for detailed steps.2. I initially planned to perform a fresh installation and configuration in each environment. Is this the best practice?
Yes, if you are planning deployments across multiple environments (e.g., Dev, Test, Prod), it is recommended to install OAS afresh on each server. Once installed, you can use snapshots to migrate content and settings.3. Are there alternative methods available, such as:
a) A cloning process?
b) Using VM snapshots?
Oracle does not document migrating entire OAS environments as these are customer specific.4. Could you provide any official documentation or guidelines on this migration process?
Yes, please refer to the following official guide:

Installations are independent and all require their unique components (like the RCU schemas being unique for each environment).
The good practise for setting up multiple environments (DEV, TEST, QA, PROD etc.) is by using response files and having a scripted installation. That way you are 100% sure that each environment is exactly configured like the others, and all have their own unique pieces.
Any cloning requires to change a number of pieces, starting from the RCU schemas in the database, the hostnames etc.
With response files and scripts for the install (could also be Ansible or other automation tools), you can install as many environments as needed, being sure they are all the same.

Hi Sherry,
Some high-level information to get started.
The official documentation would have you migration your content (via snapshots) between environments initially, then there are other methods such as catalog archive/unarchive for "finer-grain" movements to update catalogs
About Snapshots
Now, how you decide to perform the installation/configuration in a higher environment would be up to your organization. Some perform complete manual (or automated - silent ) installations based off of "gold images". Others, use containerization/virtual machines (manually or automated).1 -
Thank you everyone for the answers. I will plan accordingly.
