Tonight we continued on going over the VMware VCP-DCV 6 objectives listed in the certification blue print. We discussed how to upgrade your vSphere environment the proper way. There are two things you need to think about before you even get started. Make sure you have proper full backups that are compatible with vSphere 6! Many times backup solutions may be a little behind with their vSphere compatibility so make sure you check that first.
The other thing to be aware of is that there is a proper order to upgrade. It's listed in many place on the VMware site, but also if you want to check out the vBrownBag with Manny Sidhu he discusses it at length as well. You also need to know what kind of database you're using for different components. For instance, with the new Platform Services Controller, which takes over some of the responsibilities of SSO among other things, you need to know whether you're going to do an embedded or external deployment because you can't really change it later. Manny recommends doing an external PSC if you can.
