As mentioned in my previous post, anticipation is building regarding the launch of VMware's new flagship product vSphere (aka VI4).
During the buildup, I thought it prudent to answer a question that has been asked of me multiple times.

VCP's on VI3 will need to recertify to keep VCP status on vSphere which is to be expected.
Lets take a look at VCP certification history tracks and see if we can relate it to vSphere.

In particular, if you were a VCP on VI2, you needed to sit an exam to recertify your VCP for VI3.
Expect a similar situation with vSphere, except for the fact that you *MAY* have to sit an accelerator course to achieve to VCP upgrade.
By accelerator course I mean a shortened 2 day "whats new and different course"

vSphere is a product that is immensely powerful and capable, as were previous versions of virtual infrastructure. I have raised concerns before around the power of the product set and a users ability to create disasterous situations if they did not understand or were not careful enough when working with the product set, this still remains a concern but with application of best practice and the inbuilt mechanisms this risk is lessened significantly. The beauty of vSphere lies in the fact that although the product is a "NEW" product, the ability to use the product set will not be hard to use or difficult to ramp up to from previous versions of VMware Infrastructure.

The launch of vSphere is a huge event, and I for one will be waiting for the information overload after the launch.
