My company put me in charge of migrating our Piwik install from version 1.12 to the latest version 2.1. We are using it for a lot of websites and the database is pretty heavy (50Gb). Does some of you have some idea how long it can take to update it? I know it will depends about the server where the database is hosted but if you have some raw estimation, it will help me.
I also have another concert related to the tracking code. Is the tracking code from 1.12 will still work after migrating to 2.1?
Thank you in advance for your help.
