Matomo combination/migration of two innstallations

Hi there,
I want to combine two matomo installation into a combined system, I’ve already found some migration docs and plugins but have not been clear here.

We have currently two installation ( and both systems are productive. In the old installation we still have a few important websites, so I want to move the websites - including all history data - to the new installation.
The change of the embedded code is not the issue, but we need the historical data also in the new matomo installation.

Thanks for your help in advance.


You can use to copy over complete sites from one Matomo instance to another. It is not possible to merge mutliple sites together.
