Query about Migration Manager for Active Directory

Ajit
over 7 years ago

Hello,

Could you please let me know if the migration manager for AD is advised to be run during business hours

Does this cause any impact to the users / services.

We have file servers , exchange , other applications also in the infrastructure.

    Hi There,
    Yes, most customers run it during the day/business hours. You can specify when the Directory Synchronization agent runs, and you can focus to one DC/GC if you want, to focus the traffic on one machine, perhaps a strong one that could handle the load. The "initial Synchronization" is the pass that causes the most traffic. Once the initial sync is done, the agent performs delta synchronizations only picking up changes.

    I hope this helps,

    Hello ,

    Thank you for the inputs. We will deploy a additional GC with very good config and if the tool connects to the GC , then no performance issues can be expected. Please correct me.

    HI Ajit,

    Well, generally speaking, there should be very little performance hit. I cannot guarantee there won't be some noticeable, but little impact to production.

    You can configure the tool to connect to the specific DC, but we have no control over what workstations or servers that DC might service with regards to authentication requests. It's also noted that you should be pointing the DSA to a 64-bit Domain Controller.

    So Technical Support cannot say that there will be no performance issues from the DC or that end users can see.

    You can use the below KB to improve performance of the sync.

    Couple thoughts here around performance management with QMMAD:

    1) It is important in the Agent Manager to configure the Domain Controllers that the tool will target. At least this way, you can advise the folks that monitor your DCs that these are the ones that will be communicated with by the DSA (or DSAs as the case may be - whether by migration sessions or the execution of directory sync).

    2) I always recommend that the configured "Domain Controller" should be the RID master if possible as this will give the best performance for object creation since it is this role that creates the RIDs for new objects.

    3) Also in Agent Manager, if necessary, you can configure hours when the DSA agent(s) will be allowed to run. This is not a start/stop schedule but rather more like "blackout" times when the normally "always running" directory sync agent processes will not communicate with the directory (assuming on-going directory sync is setup).
