I have been struggling to get the AD LDS instance schema upgrade to match with the Active Directory Domain. LDS instance is synchronizing data from active directory. Domain was upgraded to Windows Server 2008 and therefore Active Directory domain schema version is 44. LDS Schema version is 30. 

I have used ADAMschemaanalyzer tool to import the difference LDIF file in LDS instance and upon manual check I see all the attributes are modified but still LDS schema version is set to 30.

Can someone explain how can I get this version incremented?

As a note, upperrange for title attribute for Windows Server 2003 is 64 and for Windows Server 2008 it is 128. After importing the LDIF file there is no change in rangeupper value for this attribute. I am stuck please help!

As per version, that I am not sure it should change merely because you created new attributes.

the upper range - I believe you are dealing with the fact that WIN 2003 is 32 bit and WIN 2008 is 64 bit.

Thanks for the reply Nosh.

When I import the difference file, the import is successful but the scheme version value in Registry (HKLM-System-CurrentControlSet-Services-ADLDS-parameters) still shows 30. It does not increment.

Any ideas why this value is not incrementing?

I am not sure why you think it should change or what does it matter on this case.

How would you check if the schema upgrade is successful if the version does not increase. If I go by the ldif import, it shows successful but it does not do anything in the background.

For 32 bit or 64 bit versions, I have tried having a Windows Server 2003 R2 x64 but edition and Windows Server 2008 R2 x64 bit edition and the problem remains the same.

When I compare the schemas it shows me 128 bit for the target domain so I am wondering if it recognizes the change in the upper values then why does it not update it when we import the difference LDF file.

Manually if I try to change the value to 128 for the title field, I can.

Hi Mansi Nayak,

May be the following information can give you some tips.

What is the best practice to remove the original 2003 ADAM SP1 instance from the configuration set once replication to the 2008 AD LDS is complete?
