i want to change version to lastest version, 2.16.0 -> 2.17.1.
but my service already use piwik, and i don’t want to have influence the service.
so i will install piwik 2.17.1 to new servers, and change existing servers-installed 2.16.0.
before the progress, i wonder if i need db migration.
if i do migrate, can i see the information of migration?
thanks, and sorry, my little english skills.
