We're not going to be able to provide you with a personalized, one-on-one, step-by-step setup guide.

Thanks it's a guide to upgrade to 6.7 but i need one with some good information with pre and post steps to follow for 6.5
Currently i have VCSA 6 and required to upgrade to 6.5.
Hope someone can help me
