I have gone through the above doc. So anything apart from that would be much helpful

Hello,

Did you check this Aricle:

Organizational Units from Active Directory in Symantec Endpoint Protection 11.0

http://www.symantec.com/docs/TECH102546

and the Thread Below:

https://www-secure.symantec.com/connect/forums/sep-11-active-directory-integration-advantagesdisadvantages

Hope that helps!!

Can Find if the client is installed with SEP
Cannot move a client. However can copy to a new group. If copied the client will be available as per the OU structure in the existing group but will be copied to the new group where policy from new group will be applied.
Cannot switch the mode manually(Use of move client utility can be done)

Anything apart from this???

Both advantage & disadvantage.

Thanks for the update. I have gone through both the links. The thread has the main info of AD sync with SEP deployment. However would like to know few more info as the above points which I have added.

Do let me know please as the information is required for some presentation.

AD Integration with SEPM only helps to retain your AD structure so that you can apply policies accordingly.OU import has nothing to do with deployment.

However once you have imported OU's and deploy SEP using Group Policy Software Deployment..all the client will go to their respective containers in SEPM. 

Find Unmanaged Computers--You can scan a whole range of IP address..which will find your computers..no need to specify any name leave that blank..You can deploy as many clients you want.

Migration and Deployment wiz--Click ok Domain click Add--Supply Domain admin credentials--s,-Skip the offline client it will add all your machines ( except the ones which cannot be contacted ) then you can start the deployment on all of them at once.

I believe its inconvenient for testing purpose ;-)
