Upgrade from zenon 6.50 tto zenon 7.2

Hi
We want to upgrade our system / database from 6.50 to 7.20.
We will upgrade OS system from window server 2003 to 2008 64bit for extension memory, SQL from 2005 to 2012.
But we still concert that zenon database upgrade from 6.50 to 7.20. Do we need to upgrade to 7.0 and to 7.20 later and do it has any restrict?
Thanks and regards
