[Reason] A heavily customized theme [Strategy] Use LTS, and skip a version: ex.: Tiki 9.x LTS to Tiki 15.x LTS. An upgrade every 36 months. Some can have concerns about upgrade difficulty but this isn't the case because if you skip ahead several versions, you are going through the same path as everyone else did in the previous years, but in an accelerated fashion. You can upgrade from Tiki 1.9.0 (released on 2005-04-27) to any later version of Tiki because all the upgrade scripts are part of the code base. This policy will be maintained to keep upgrades as easy as possible. [Main concern] 
I want to upgrade less often
