Best practices for public folder preparation before migrations

Kinda worried about following through with the recommendations from the ValidateMailEnabledPublicFolders.ps1 script. There's a PublicFolder object named "Schema" in Microsoft Exchange System Objects. I'm reluctant to delete anything named "schema" in a database, but its weird seeing it with the objectClass of PublicFolder. Is this safe to delete, or have any guidance on determining if its safe to delete, or better to just continue with the migration and ignore it? 

Get-ADObject "CN=Schema,CN=Microsoft Exchange System Objects,DC=***,DC=***" | fl


DistinguishedName : CN=Schema,CN=Microsoft Exchange System Objects,DC=***,DC=***
Name              : Schema
ObjectClass       : publicFolder
ObjectGUID        : 9*******-8***-4***-8***-2***********

Any help would be appreciated. Thanks!
