Hi guys,

I would upgrade my wiki but like you can see i have a large difference between the versions.

How i can know the risq of the upgrade ? Can i update any problem (data) ? Do I need to go through an intermediate release ?

Thanx for the response ;)

The most important thing is that you have a working backup.

Also you might need to change the PHP and maybe also the MySQL version.
