Upgrade from older versions
UPDATE FROM JOOMLA 1.7
Well, that's an easy one.
Visit Extensions → Extension Manager → Update
click the button and your done!
It's the time to relax, grab a coffee and think:
Well, it was a good decision to start my new project with Joomla 1.6/1.7
Attention: Many text strings in the language files are changed. The one-click update doesn't include
local language packages. If you have installed local language packages it is necessary to update those, by
reinstalling.
In case you think this 'one click solution' is far too easy. It cannot be true! Have a look at the more
detailed Joomla documentation

MIGRATE FROM JOOMLA 1.5
How7can you migrate a Joomla 1.5 website to Joomla 2.5 without loss of data7or similar disasters?
There are two ways to complete the update:
1. You can update the existing Joomla 1.5 website7 by using an additional component. This
component loads all the necessary files7with one click to your Joomla 1.5 website and automatically
converts them to Joomla 2.5.
2. You can7 create an empty7 Joomla 2.5 website and insert the data7 from the Joomla 1.5
website7manually.
Auto upgrade from Joomla 1.5 to Joomla 2.5
WARNING: The upgrade component I am using does7 not allow7 the transfer of data from ALL
third-party components.
But, generally, I think the idea is a good one. :-)
Before you begin, please answer the following questions with a loud and clear YES.
