Forum What will I lose in upgrade?
 

I am running 3.8.4 and I am going to upgrade to 4.0.3 today, MAYBE.

I just purchased the standard forum script instead of the CMS.

What will I lose when I upgrade as far as functions?

I already know I cannot use the blog, and I'm sure I will need to upgrade some 3rd party addons, but what else will not be there that I am used to?

Also, I am using the default template currently, Will I still be able to use the default that I have used as far as my custom header and such?


Thanks in advance!
