How to download it?

As usual, that’s very simple. You either download it via the well-known

• MOS Note: 2485457.1 – AutoUpgrade Tool

or you fetch it directly from oracle.com with curl, wget or by just clicking on the big button.

What’s new?

Again, a lot. 25.6 release has a significant and important number of enhancements. It includes the fixes and enhancements for 25.5 as well. 25.5 is the version included into the 19.30 January 2026 Release Update whereas 25.6 is the slightly newer version available on My Oracle Support and oracle.com.

build.MOS_NOTE 2485457.1
build.MOS_LINK https://support.oracle.com/epmos/faces/DocumentDisplay?id=2485457.1

The highlights this time are:

• Enhanced MS Windows support for download and patching, e.g. not requiring an admin account anymore for downloading and better oradim support
• Patching and download support for Oracle Database 21c and Oracle AI Database 26ai
• Download and apply of the JDK – this is super-useful and a great relief
• Download and apply dNFS patches

One limitation is important to mention: We don’t support upg1.target_version=26 even though a grep may tell you.

[oracle@caldbcs1 ~]$ grep 'target_version' /home/oracle/auto_config_26ai.cfg

# <prefix>.target_version
#upg1.target_version=12.2|18|19|21|23|26

Right now you need to use upg1.target_version=23, please. Technically, this is fully correct but we understand that you may want to use “26” when we call the release now officially Oracle AI Database 26ai. The support for “26” will be included in the next release of AutoUpgrade.
