Dear all
As the IFS system administrator, I am reaching out to seek clarification regarding the possibility and requirements for upgrading our Oracle Database from version 19.10 to 19.27. Please provide guidance on the following points:
1. Is a Seamless Upgrade from 19.10 to 19.27 Supported?
We would like to confirm if it is possible to perform an in-place (seamless) upgrade of the Oracle Database from version 19.10 to 19.27 without causing disruptions to the IFS Applications environment, assuming both versions are within the certified Oracle 19c release family. According to IFS documentation, the latest available release update within the supported Oracle Database versions is generally recommended and supported, provided that the upgrade stays within the certified release family and follows IFS guidelines12.
2. Are There Any Special Procedures or Documented Requirements?
Please clarify if there are any special procedures, prerequisites, or documented requirements that must be followed for this upgrade. Specifically, we are interested in:
-
Any official IFS documentation or checklists for upgrading Oracle within the 19c family.
-
Required pre-upgrade steps (e.g., backups, environment validation, compatibility checks).
-
Post-upgrade actions or scripts that must be executed to ensure full compatibility with IFS Applications.
-
Any limitations or known issues when upgrading to Oracle 19.27, especially regarding multitenant architecture or deprecated features31.
3. Summary Table: Oracle 19c Upgrade Support
| Current Version | Target Version | Upgrade Supported | Special Procedures Required | Notes |
|---|---|---|---|---|
| 19.10 | 19.27 | Yes, if certified | Yes, follow IFS guidelines | Use latest patch, check documentation13 |
4. Additional Information Requested
-
Is there a specific IFS support document or knowledge base article that outlines the exact steps for this upgrade?
-
Are there any mandatory scripts or manual interventions required during or after the upgrade process?
-
Should the upgrade be tested in a non-production environment before applying to production, per IFS best practices?
5. References to Official Documentation
We kindly request links or references to official IFS documentation regarding supported Oracle versions and upgrade procedures for our records and compliance13.
Thank you for your assistance. We look forward to your detailed response to ensure a smooth and compliant Oracle Database upgrade for our IFS environment.
thank you in advance for any information
