We are looking to upgrade from 1.1.1 to 1.3 for a small Piwik server. We had tried to go to 1.2 but problems forced us to revert to a backups.
Can we just use the button on the the site for this upgrade?
I assume it will update the files then will run the database updates in sequence to go from 1.1.1 to 1.2 to 1.2.1 to 1.3. Is that correct?
