Lars Eirik R	Wednesday 07 April 2010 1:33:55 pm Hi. I am currently running version 4.1.3 and need to upgrade to 4.2.0 I have modified some of the ezwebin classes with additional fields. If i upgrade to a new version of the ezwebin classes , for instance the article class i am given some options: The one i would like is to replace existing class (Warning! 195 content object(s) and their sub-items will be removed) 1Does this really remove all of my articles, meaning i lose all my content? There has to be a good way of understanding how to successfully do upgrades, but i have not gotten any good responses before when asking. Please help me.

This way, you will keep your existing data. Do not forget to backup your database before. Cheers, Hakim Bouras PRISMALOG - Creation de site Internet

Hi.

I am currently running version 4.1.3 and need to upgrade to 4.2.0

I have modified some of the ezwebin classes with additional fields.

If i upgrade to a new version of the ezwebin classes , for instance the article class i am given some options: The one i would like is to replace existing class (Warning! 195 content object(s) and their sub-items will be removed)

1Does this really remove all of my articles, meaning i lose all my content?

There has to be a good way of understanding how to successfully do upgrades, but i have not gotten any good responses before when asking.

Please help me.

Hi Lars,

I would suggest you to update the existing classes manually from the admin interface, by comparing your class definition and the class definition from a clean 4.2 install. This way, you will keep your existing data.
