Thank you! I have erlier read about upgrading to XF2 and then saw that it wasnt so easy. But I will try with a little help.XF1 to XF2 is a major upgrade.
Ensure you plan and test accordingly.
Donwload XAMPP and install it on your windows for example.
Move your XF directory files (your backup files) to htdocs folder which was created when you installed XAMPP.
Upload your database (your database backup) by either using localhost/phpmyadmin or by using shell.
Configure the config file.
Then you have on your local machine a copy of your live server. And do a test upgrade there.
Thank you!As you have no addons installed, it should be pretty straightforward without problems. Just upload the files, click on upgrade and done.
However, make a backup of your files and database first. Don't do any upgrades without having a backup.
And if you can, do a test installation on your local machine first to see how it goes.
