Hi all, I’ve been migrating my Piwik instance to a new better spec-ed server. In doing so, I took the opportunity to also upgrade the Piwik from 2.12.1 to 2.16.0 (the latest when I did my setup few weeks ago).
On the first day of switch over, I noticed huge differences in the report. The new version of Piwik (2.16.0) shows much higher stats in general compared to the older one (2.12.1). So much so I need to reverted back to the old version while I am trying to figure out what happened and which one is correct.
To rule out that it is a tracking issue, I set up a test Piwik instances for the two versions, import IIS log for the same day using python import script, and I can confirm that the report generated is very much different. The older version (2.12.1) shows 1,708 visits and the new version (2.16.0) shows 68,504 visits.
Regardless which one is more accurate, what possible technical explanations for this discrepancy. Both two version installed on the same server, imported from the same IIS log file.
If someone could possibly tell me how I could investigate this. Thank you.
I just installed version 2.16.1 and use the same configuration as the one I have for version 2.12.1 and the result is consistent, ie. I have the same result for 2.16.0 and 2.16.1 and that result is greatly different with 2.12.1
In your reports from 2.12 VS 2.16 where do you notice most differences, is it located in particular page URLs, or maybe particular user configurations? Or do you think the data is tracked less overall?
