Hi,

I want to upgrade SEP 11 to SEP 12.1, I can deploy from SEPM.

But can I export install package from SEPM then run the file to upgrade directly on target server without uninstall SEP 11 ??

Thanks

Absolutely. SEP 12.1 will upgrade right over 11.x clients. This is no problem. You will need to reboot though to complete the upgrade.
