Upgrade minor versions

[ottopodo]

Hello,
I need to upgrade an existing 3.4.a installation to 3.4.b
Do I have to follow the common upgrade instructions?
Is it possible to patch existing installation without reinstall a second instance?

Yes, just put the new WAR file in the webapps folder.

However you should make sure you have a working backup first, just in case.
