Update to Jupgrade tutorial - common migration problems solved

Now that Joomla 2.5 is upon us, and support for 1.5 will be going away, the decision to migrate is a hot topic. We wrote a great tutorial on migrating using Jupgrade in July, "Migrating from Joomla 1.5 to 1.7" that gives you all the basics. Start by reading that article. The most frequently encountered problems and their solutions are outlined here.

Step 1. Undefined Property...

Right after you click Start Upgrade, you may get this message. This one is especially likely if you are upgrading your development copy on your local computer. The message reads:

Notice: Undefined property: stdClass::$timelimit in C:\xampp\htdocs\j15\administrator\components\com_jupgrade\includes\jupgrade.class.php on line 156
OK

Here's how to fix it.

Go to Components, then Jupgrade, then the Parameters icon.

Change 'disable set_time_limit' option to 'Yes' under jupgrade parameters. Most of the time this is set to No. You only need to try this if you get the error message. If you don't get an error message don't change it.

Step 2: Jupgrade hangs when trying to decompress package

You may get an error, Zip File not found while decompressing package. Or the process stalls at this stage and never finishes decompressing the package. Be patient with this step it can take a while.

Click the Parameters icon as you did before. Change the settings
Skip Checks = No
Skip Download = No
Skip Decompress = No

You should now be able to complete the process. If you can't, and you're one of our students, let us know the exact problem and we'll track it down.

Above is a screenshot of the settings I used on a migration of 1.5 to 1.7 on my XAMPP local server. I had no problem with these settings and you might want to use them as a guide if you are having problems.
