Before you try APM on a testbed or on your system, have in mind the following:

•The APM consists of a series of automated procedures that require many mandatory prerequisites.

If such prerequisites are not met, the APM won't work at all or will work badly or only partially.

Therefore: before starting your first APM testing session, check that all the APM prerequisites are met.

See the Automated Page Make-up Prerequisites chapter for more information.

•The APM is being constantly updated and enhanced. The first GN4 version with a complete APM is 2.5, starting from build 3049.

Do not try APM in GN4 versions previous to 2.5. See also How to know the APM version?
