Dear all,

I need a:  

- script to migrate clients SEP to a new SEP  Server;

-  script to install SEP client remotely;

-  script to detect machines that do not have client SEP  installed;

could someone help me?

 Best Regards,

You can do the first two using the SEPM and auto-upgrade feature or using the client deployment wizard.

For the last one, you can use an unmanaged detector to detect unmanaged clients and than push SEP to them

As far as scripts go, the below threads that I've been a part of decribe ways to redirect clients to a different by script, and install by script.

YMMV, so test thoroughly and all that.

AFAIK, you dont need to script to do any of these, 

Once SEPM is installed, use this to mirgrate clients.

to know which clients do not have SEP installed you can use unmanged detector

What does it mean to set a client as an Unmanaged Detector?
