3.8 to 4.0 upgrade
 

Sorry if i am an idiot an overlooked the information. I am sure someone has had to ask this already.

I have 3.8 installed* I purchased the blog component as well as I have photopost pro* vbadvanced cmps and vbseo integrated. I am using a custom theme as well as a few mods like a twitter* facebook and video feature.

With upgradeing to 4.0 will this all continue to work relatively problem free?
