You can upgrade from any version of Abiquo 3.0.0-GA or 3.x version to the latest Abiquo version.
Previous steps, backup, stop services, blah blah blah
Perform the packages upgrade
This step must be done on all Abiquo servers, including Abiquo Management Server, Remove Services, KVM Servers and LVM Servers.

Install destination repo package.
There is one package for each major version that installs base and updates repositories, please locate the abiquo-release-ee package of your destination version and install it with next command, for latest abiquo version this would be
yum localinstall http://mirror.abiquo.com/abiquo/3.6/os/x86_64/abiquo-release-ee-3.6.0-2.el6.noarch.rpm
Update yum cache
yum clean all && yum makecache
Update abiquo packages

This step must be done on the database server.
Main Abiquo database
Ensure your hostname is in your DNS or in your /etc/hosts file.
abiquo-liquibase [-h DB hostname] [-P DB port] [-u user] [-p password] update
Is there a known issue with upgrades from 3.2 versions where next message appears and fails to apply the liquibase update:
Liquibase update Failed: Validation Failed:
