Impact of SEPM with AD Integration

Hi,

We are planning to integrate our SEPM with the AD. But I am not sure about its impacts on the existing environment.

Recently two month back we migrated the SEPM from v11.0.6300 to v12.1.4. And we have around 1200+ clients SEP.

We have around 20-30 groups (including the sub-groups) and the policies for each group is different from other. So can some one please enlighten me about the full impact of this migration on groups, policies, clients and the client-server communication.

Thnaks in Advance.
