Are you migrating to Sophos Central or Sophos Enterprise Console? If it is Enterprise Console, you'll want to set up your server before migrating your endpoints over. Sophos server installer includes a competitor removal tool that should be able to remove Symantec so long as there is nothing in the software that would prevent a standard uninstall. Turn off any uninstall prevention features in Symantec and simply run the install on the server. If this works without issues you can look to start pushing out to the rest of your environment. Enterprise Console deployment is covered in the doc listed previously and Central deployment documentation is found here.
