How to upgrade Joomla from 1.5/1.6 to 2.5

BEFORE APPLYING ANY CHANGES YOU SHOULD CREATE A BACKUP

1) Go to http://domain/administrator => Extensions => Install/Uninstall => Upload Package File “com_jupgrade-2.5.1.zip” => Upload File & Install

2) Extensions => Plugin Manager => find “System - Mootools Upgrade” => Enabled “Yes”

3) create “jupgrade”subfolder in RootDirectory (/var/www/public_html/jupgrade), change owner to Apache user and change permissions to “777”

4) Download “http://joomlacode.org/gf/download/frsrelease/16804/73116/Joomla_2.5.3-Stable-Full_Package.zip” (download link: http://joomlacode.org/gf/project/joomla/frs/) to this directory (./jupgrade) and unpack

5) Go to http://domain/administrator => Components => Jupgrade => Parameters:
Distribution => Joomla 2.5
Skip checks => Yes
Skip Download => Yes
Skip Decompress => Yes
Enable migration debug => Yes
Enable Mootools version debug => Yes
DO NOT FORGET “Save” on the top and close this window.

6) Press “START UPGRADE”

7) After upgrade you should check all links. You may do that via “Xenu's Link Sleuth”.
This program works under Fedora, Red Hat, Ubuntu (use Wine) and Windows.
You may download it from “http://home.snafu.de/tilman/XENU.ZIP”, just unzip, install and start under Wine.
1) Go to “File => Check URL”
2) Enter “http://domain/jupgrade/”, NOT http://domain/jupgrade, DO NOT FORGET the last “/”.
(More about this program: http://home.snafu.de/tilman/xenulink.html)

8) If all looks fine - create another subfolder “my_old_joomla” in RootDirectory and move all content FROM RootDirectory to this subdirectory (from /var/www/public_html/ to /var/www/public_html/my_old_joomla) except “jupgrade” and “my_old_joomla” folders.

9) As we can see the RootDirectory is contained only two folders “jupgrade” and “my_old_joomla” you should move all content from /var/www/public_html/jupgrade to /var/www/public_html/

10) That’s all.
