Import analytics data from Piwik to Matomo on new server

Question

Piwik: 2.11.2
Matomo: 3.14.1

Currently I am using Piwik for tracking visitor analytics for over 100 websites and I am planning to switch to a newer Matomo version on a different server.

I would like to take the analytics data from Piwik and import it into Matomo. There doesn't seem to be much information about this type of move. In my search I have found somewhat similar questions:

• https://forum.matomo.org/t/importing-data-from-piwik-1-11-1-to-matomo-3-3-0/27209

Is it possible to import the data to the new instance without first upgrading Piwik?

Before I start the process of importing the DB, has anyone made this type of move before and is there anything in particular that needs to be done?
