Hi Tim,
Before I deployed secondary SMS, I have enabled EndPoint server. I moved it dedicated server and disabled Endpoint Mgmt and install DB.
Initially with secondary SMS, there was issue with DB Sync between SMS servers, because of Product mismatch. I fixed it by by modification of scheme.c file as described:
Synchronization fails when SmartCenter servers contain different Check Point products 
The Command: 
./migrate export --exclude-uepm-postgres-db <migrate export output file name>
It is not working.
It seems that EndPoint is still running, and it is starting after reboot.

I am still not able to run migrate export.
I will try to search how to fix it. Anyway if you have an idea, please let me know.
Thank you for reply.
