Hi Alexander.
Yes, you can send a task to run the command to change the NS.
By the way, I'm working at the moment in a project doing exactly that. My task target are all computers that has been resquested a new policy in the last 15 minutes. (except NS - **Don't forget to remove NS from your target). The task works extremelly well, but you have to monitor the migration because some agents you will have to migrate manually.
I'm attaching the script bellow. **Also don't forget to configure the task to run in "Hidden" mode to not show any screen to the user.
@echo off
cd /
cd "%ProgramFiles%\Altiris\Altiris Agent"
AeXAgentUtil.exe /Server:your_new_ns.domain.com
exit
Regards,
