I have an old Piwik version : 1.1.1 and I would like to update it with the latest (2.0.3). My problem is that the direct upgrade 1.1.1 => 2.0.3 doesn’t work because of a SQL error : “Unknown column ‘config_md5config’ in ‘log_visit’”. The problem is that this column isn’t in the 1.1.1 version and some requests need it.
I thought to upgrade each version for less errors : 1.1.1 => 1.1.2 => 1.1.3… but the problem is that the database is very big : about 17,000,000 entries for 3.8 Go so one upgrade is very very long. And I have to do it in a development environment before do it in production…
So could you help me to upgrade my Piwik please ?
Thank you !
