Knowledge Base Help & Documentation:
Does the migration include the transferring of Google Analytics code or some other analytics system?
Unfortunately no. CMS2CMS automated migration service doesn’t migrate it automatically.
In order to take the existing analytics code from your current site (located on server-A), and transfer it to your new site (on server-B) simply use the same GA tracking code and implement it on the new version of the website located on your new server.
Note: Even if the domain is different, you can use the same tracking code.
