I maintain a Piwik installation on a remote VPS that runs on Ubuntu 10.04. I tried to update my Piwik, but it failed with the following error message and now I can’t access Piwik any longer.
“To run Piwik you need at least PHP version 5.3.3
Unfortunately it seems your webserver is using PHP version 5.3.2-1ubuntu4.28.
Please try to update your PHP version, Piwik is really worth it! Nowadays most web hosts support PHP 5.3.3.”
Unfortunately I am not the administrator and the sys admin does allow non-official sources, so I won’t get this PHP update and will have to downgrade Piwik. As far as I know, Piwik 2.7 is the latest version that still supports PHP 5.3.2.
What is the safest way to get my Piwik running without losing any data?
My strategy would be to use PHPMyAdmin and get a full SQL dump, then install Piwik 2.7 afresh and restore as pointed out in the FAQ.
Is that the right way? Might the update to the latest version have changed my database in a way that makes it non-downwards compatible?
