If you want to become a VCP5, the following is your options:

1. New to VMware (no courses, no certifications) – Attend the 5 day “Install Configure Manage” course. Then do the test

2. Already VCP3 – Take the 2 day “vSphere 5 Whats New” course. Then do the test

3. Already VCP4 – Go directly to the VCP5 test. No courses required. (until 29 Feb. 2012)
