LAPS Deployment

Hi Support,

I need your expert advice on the following:

I want to implement LAPS (Local Administrator Password Solution) in Domain Environment. Before Implementation of LAPS i need to some sort of queries as per following:

Current Environment:

• OS: Microsoft Windows Server 2008 R2 SP1 (Enterprise)
• Active Directory: Windows Server 2008 R2 SP1 (Enterprise)
• Forest Functional Level: Windows Server 2003 R2
• Domain Functional Level: Windows Server 2003 R2
• Client Windows: Windows XP, Windows 7, Windows 8 and Windows 10 

LAPS Implementation requirements that schema will be update before deployment LAPS.

1. What will be impacts and what will be face challenges as per current environment?
2. If we update schema on Active Directory 2008 R2 SP1 Enterprise and then deploy LAPS on this current scenario then will it need to upgrade forest function and domain functional level before LAPS Deployment?

Kindly assist with your expert opinions.
