问题
We have already Joomla´s version 1.5.14 from 2009 to make our homepage setting. Now we want to upgrade the version to 3.0.
We have made a test page 3.0 and compared it with our original page. We understand that files and the database have been subject to changes, so it´s difficult for us to see how we can practically move our data to the new version.
We have discovered that with regard to the version 1.7 it is pretty easy to upgrade to the new version. We have studied your Joomla manual, but we still have problems to get it right. Have you ever yourselves tried to upgrade a similar situation?
Can you possibly give us some hints how to do it?
It would help us if you could suggest the steps you want us to take?
You now, it´s not so nice to go through a huge number of manual pages.
As you can appreciate I have taken back-up on the data base and the files. I´ve come that far and need your help to proceed further.

Fear not, upgrading from Joomla 1.5 to 3.0 isn't hard at all. There are 2 really good extensions that allow you to do this:
jUpgrade and SP Upgrade.
Both allow you to upgrade to either Joomla 2.5 or 3.0
I would first recommend updating to the latest release of the 1.5 series (1.5.26) before using one of the extensions. To do this, simply download this package, upload to the root of your Joomla site in the FTP and extract it.
May I just point out that Joomla 2.5 is still the recommended version to use as it is the long term version, where as Joomla 3.0 is short term till Joomla 3.5 is released.
