I have been using Piwik on client sites for quite some time now and all is working well. When I install Piwik it is always on their own personal client domain e.g clientone.com/analytics or clienttwo.com/analytics
I also have my own single Piwik installation on my personal hosting account e.g mydomain.com/analytics which tracks my personal website.
My question is, can I monitor all of my client sites, AND my personal site from within my Piwik dashboard?
Ideally I would like to login to mydomain.com/analytics and see all of my client sites statistics. I don't wish to alter or change their Piwik installs at all, so is this possible without having to export/import the database etc? I am hoping I can simply modify tracking codes or similar?
I know I am able to add additional sites to my Piwik dashboard, but this involves installing a new tracking code on the sites I wish to monitor. If I install this new tracking code will my client sites not lose all of their existing data?
