Upgrade from Joomla 1.5 to Joomla 3.4

Hi, this upgrade is possible? or is better in two steps? first from J1.5 to J2.5 and after J2.5 to J3.4?

Can you guide me?
Thanks a lot!

Migrating from J 1.5 to J 3.x in a single step is possible, although is not a walk in the park:

The migration from Joomla! 1.5 to 3.x is a major migration. There are many changes in features and database tables between these two version. It is NOT a one-click update. You will be building/installing a fresh Joomla! 3 installation and then migrating (moving) your data into it.

docs.joomla.org/Joomla_1.5_to_3.x_Step_by_Step_Migration

We published two tutorials that explain how to to succesfully migrate a Joomla 1.5 site with Custom Properties to Joomla 2.5 and then to Joomla 3.x.
www.solidsystem.it/how-to-and-tutorials/...es-to-joomla-17.html
www.solidsystem.it/how-to-and-tutorials/...25-to-joomla-3x.html

In any case, it won't be a straightforward process. There are several elements that can't be migrated automatically and/or requires adjustments and tweakings (template, modules, some third party extensions that might not be available for J 3.x, etc)

Some might argue that's indeed more practical to build a J3.4 site from scratch, and migrate the data using dedicated tools or SQL queries.

Hello Andrea,

Ok, we have installed a fresh J3.4. And we have migrated content with J2XML Extension (articles, categories and users)

BUT: Do you now to migrate CP tags, labels, etc. from our actual J1.5 CP Version 2.0.4 to the new J3.4 CP Version 3?

PD: i know a little of "mysql myadmin", "tables", etc. So if the instruccions are sql queries, please explain it detailed to follow them.

Hi,
here's an old post on this very subject (with queries and all).
