I would say it depends on what features you need for the deployment. But in general I'd say that version 13.1.1.4 is a stable version to upgrade to.

It's a Long-Term Stability Release with the latest Maintenance Release. So it contains many of the newer and expected features with only bug fixes applied.

I personally believe that it's still a bit early to upgrade to 14.x because I have seen some weird problems in a customer's lab environment who jumped to 14.1.0.2.

But I guess I'm a bit of a chicken when it comes to upgrading to newer versions. :P

I hope this helps!

@Philip, are you able to share any high level details on the weird problems you were seeing in a customer's lab on v14.1.0.2?

You can use 13.1.0.8 and 13.1.1.4 is good choice as well. Hope this helps...

I recommend to never install a version before X.1.1 and always install the last release point (wait a couple of days to make sure there is not a huge bug included in the new build)

it depends... if there is a new necessary feature, you have to take this release. So look at release notes for new features and for known bugs. Don't choose a x.0.0.0 release.

Basically x.1.x.x are long time support releases x.0.x.x are standard support releases look at K5903

we are running 14.1.0.2 and 13.1.x.x in production environments. We did run 11.6.x for a long time.

In K5903 article, look at this text

Each x.1.0 release marks the start of the Long-Term Stability Release. The initial release (x.1.0) contains new features, stability improvements, and new hardware support. Subsequent maintenance releases (x.1.1 to x.1.n) address product defects, security fixes, diagnostic and supportability improvements, minor functional improvements, and new hardware support.

The problem with new features is it can create new bugs... one example of this on version 14.1.0 is :

This bug is fixed in 14.1.0.2
13.1.1.x also has unfixed critical bugs. ;-)

And thats threason for my line "look at release notes for new features and known bugs"
