Please Protect the 1.5 Page

Could someone please protect the page containing the instructions for the migration from version 1.5 to the later versions? It keeps disappearing. Elin? Chris?

Need of a re-write

Think perhaps this article needs to be written for 1.5 and 2.5? Isn't relevant 1.5 at all, as noted below it looks like 1.6 to 2.5.

Why a re-write? Is 1.5 -> 2.5 that different from 1.5 -> 1.6? If not, why not at least bring back what used to be here before it got blown away? This is very annoying for me, as I was just attempting a migration from 1.5, and now the page I was consulting has vanished...

What URL were you looking for? There was a fault in the wiki database that caused some issues and which should now have been fixed. If we are still missing a redirect I can easily re-instate it. Chris Davenport 08:49, 29 January 2012 (CST)

The migration from 1.5 to any later version as presented in this article is incomplete. It may be too much for one article but there are three articles in play here: this one, Migrating from Joomla 1.5 to Joomla 1.6+ and Upgrading a Joomla 1.5 template to Joomla 1.6. (Is it possible to move from 1.5 to any later version without revising the template?) Can these three articles be merged so that the migration instructions from 1.5 to any later version are in one document?

cmb 11:26, 29 January 2012 (CST)

Ahh, I mistook this article for one of the above. Got it now...

Is It Time to Change the Title of This Article?

Now that 1.6 and 1.7 are deprecated and 2.5 is here, should the title of this page be changed? Perhaps it would be better to leave this one in place and create a new article with the title of Migrating from Joomla 1.5 to Joomla 2.5.

cmb 21:04, 25 January 2012 (CST)

Yes. Hmm. I got the redirect the wrong way round. I'll fix it when I get back from work. Chris Davenport 23:59, 25 January 2012 (CST)

Hmm, indeed. When I wrote the question above, there were no redirects in place. Now I can't find the original article. It looks like there's a loop somewhere, Chris.

cmb 11:39, 26 January 2012 (CST)

Well, I have no idea what went wrong but I basically had to delete all pages related to this page and re-create it from the logs. Hopefully, all working again now. Chris Davenport 15:50, 26 January 2012 (CST)

Correct me if I'm wrong but doesn't this article only describe how to upgrade from 1.6 or higher to 2.5?

Add PHP Check

Please add PHP check to the update script. If version==4, then prompt "Please upgrade your PHP"

Otherwise the error message is "Fatal error: Only variables can be passed by reference in /var/www/html/administrator/components/com_jupgrade/views/cpanel/view.html.php on line 35"

install mootools plugin, switch to a default template

you might want to add two requirements:

  1. install the mootools plugin
  2. switch to a default template first

Without mootools the installation process got stuck (from 1.5.2), using a custom made template, too. --Marek 17:27, 7 February 2011 (UTC)


I added the install the mootools plugin section (without screenshots) --Weissollo 22:09, 9 February 2011 (UTC)

I added a section that describes how to manually upgrade joomla. If anyone has anything to add to it, please feel free.

To the previous poster here: I don't want to play down your efforts - but as far as I can tell, the database part of the migration definitely does NOT work that way. First off, there's actually no need to change the prefix; and second (and far more importantly): you can't simply import a 1.5 table dump into 1.6 tables! They have completely different structures; I can't really tell for 1.6 at the moment, but 1.7 e.g. has no name column in article anymore, but an asset_id... and many more changes to the columns! So you'll definitely need some kind of migration script here! Since I did the migration via JUpgrade, I don't have any working manual upgrade instructions at hand either at the moment, so I unfortunately can't contribute much constructively here, but I'll change the section so that it becomes clear that it still needs work to be complete.
