I have a challange. My board is old (1.2.4) with templates that I've purchased and installed (2013). I tried once to directly upgrade from 1.2.4 to 1.4 without success. You can read about it here: Old topic.
Board: No problem to import from old to new.
Template: I have changed some some bits here and there which I can't remember.
Add-ons: I have some addons which I would like to keep.
A total new installation would be last resort as I would like to keep my settings and configurations (template wise) as it is without having the need to install a brand new board and to it again.
My question is: How can I do this as flawless as possible?
