Hi,, please check these lins..

How to check the schema version?

Moreover, I guess schema analyzer tool will be helpful to compare the schema pre and post extensions.

Moreover in community already a similar thread has been discussed...

dsquery * “cn=schema,cn=configuration,dc=domain,dc=local” -scope base -attr objectVersion 

Open in new window

on any of your DC and compare the output version with below table

13 - Windows 2000 Server
30 - Windows Server 2003 (realease 1)
31 - Windows Server 2003 R2 (release 2)
44 - Windows Server 2008 (release 1)
47 - Windows Server 2008 R2 (release 2)
51 - Windows Server 8 Developers Preview (new server edition; now only in Developer’s preview for MSDN subscribers)
52 – Windows Server 8 Beta (publicly available)
56 - Windows Server 2012

You can use the following powershell command on one of your DC:

Get-ADObject "cn=schema,cn=configuration,dc=YOURDOMAIN,dc=LOCAL" -properties objectversion

Depending on the objectVersion it outputs you can figure out if your schema has been extended for Server 2008 (R2) or not. To get a quick idea of what the numbers are

30 -> Windows Server 2003
31 -> Windows Server 2003 R2
44 -> Windows Server 2008
47 -> Windows Server 2008 R2

Hope this helps.
