Hello Juan,
It's definitely possible to upgrade from 1.4 to 2.0 but you need to embrace the change that there is a major overhaul of EasySocial's look and feel
What I noticed is that, people tend to stick to the same layout forever and not comfortable with major design changes. This is why 40 - 50% of websites that are still alive looks like geocities
(no pun intended)
Anyhow, as long as:
1. You did not hack any codes
2. You are fine with design overhauls and move with technology
3. You love new and fun toys
You are good to go
