Upgrade from oldschool

Upgrade from oldschool

Tuesday 11 March 2008 8:52:48 pm - 4 replies

I'm currently working on a very old version of eZ(2.1) which has been modified pretty heavily. I'd love to bring it up to date, but in addition to having to deal with the customizations that were made(by someone else) I've been totally unable to locate any documentation on upgrading from a version this old.

Any thoughts/suggestions?

I couldn't find any doc on upgrading from 2.2.x to 3.0.x, but it's probably a lot easier to start with a fresh site and move your content manually or automated with rss or some other means. And you don't have to figure out what modifications / hacks are done on 2.1 this way..

Some reasons:
* 3.x ( and 4.x ) is very different from 2.x, the only thing you might succeed in upgrading is the content.
* upgrading takes a lot of time, especially when you need to upgrade from 2.1 -> 2.2 -> 3.0 -> 3.1 -> 3.2 -> 3.3 -> 3.4 -> 3.5 -> 3.6 -> 3.7 ( and change to php 4.4) -> 3.8 -> 3.9 -> 3.10 -> 4.0 ( and change to php 5.2)...

Thanks for your quick reply. My reason for wanting to upgrade is to keep some of the functionality that has been custom coded by another programmer. I'm not familiar with the changes he made (and there isn't any records of it beyond commented code). Keeping this functionality is pretty important - but obviously not as important as keeping the content. I also hadn't considered the change to php 5.2, so keeping much of the old code is probably out of the question.

I hadn't thought of using RSS to keep the content, thank you very much for that idea. Does 2.1 support RSS? I'm not sure about another method. Can you elaborate?

No idea, never actually used 2.x my self.
And the only info I could find was this:
http://doc22.ez.no/

Earlier there was a quite big unofficial community site for 2.2 users, with upgrade scripts to 3.0 and a php 5 port of 2.2. But seems to have vanished..

Seems like a total loss then(edit: in terms of perserving functionality). All these factors <i>seem</i> insurmountable. Thanks for such good advice!
