Joomla > from 3.4.8 to 4.1?

<< < (2/2)

Walter.Ego:
I'm really sorry... I'm a bit confused.
I'm trying to start again...

I have mywebsite.com (joomla 1.5.26 - CiviCRM 3.4.8.) and mywebsite.com/update (before I installed a new versione of Joomla and CiviCRM but now I try to copy my old site and upgrade joomla and CiviCRM).

I'll let you know if I have a problem.
Sorry and thanks for support

gchancy:
I think the fundamental disconnect is about how Joomla migrations occur from 1.5 to 2.5. To get to 2.5, you build a completely new site. If the JUpgrade utility works for you, which I have never gotten it to work, the new site uses tables in the old DB that have a new prefix. JUpgrade may, potentially, migrate the CiviCRM tables. I have never gotten it to work, so I can't comment.

The other method is SP Upgrade which only does:

Users
Articles (along with their Sections and Categories)
Contacts
Web Links
News Feeds
Banners
Images
Menus
Modules

So that leaves you with all of your CiviCRM data stuck in an old DB tied to a 1.5 site that you are replacing.

Unless someone has a better idea, the only path I see is exporting all of the data from the old and importing it to the new.

Am I missing an easier method?

Hershel:
What you can do is install CiviCRM on your new 2.5 and then use MySQL (phpMyAdmin perhaps) to move the old tables from the old install to the new. Then all your data is there. You may have to then run the CiviCRM upgrader if it's a different version. See here http://wiki.civicrm.org/confluence/display/CRMDOC41/Moving+an+Existing+Installation+to+a+New+Server+or+Location for more details

Walter.Ego:
thanks for information.
I didn't it but I migrated old tables and then I upgraded the new version of CiviCRM.

Now I have a new version of CiviCRM and everythings works well on my backend but on frontend I have error CiviCRM 101.
Any CiviCRM menu item I create results in a "CiviCRM-001" error page.

Could it be the result because I didn't what you suggest?

Thanks

Hershel:
Seems you posted this same thing here:
