Our current SP 2010 farm uses classic-mode authentication. We would like to migrate to claims when migrating to SP 2013. What is the best practice here? Migrate to claims on SP 2010 or first move databases to 2013 in classic mode and upgrade to claims on SP 2013?
From what I see online migration to claims is just a Powershell code that needs to be executed. Any possible problems with that? Any best practices?
