Migrate from Endpoint protection 12.1.1 to Protection Suite Enterprise 4.1

Hi,

1. Symantec Endpoint protection manager  version 12.1.1101

We currently use the above  Symantec product. This product   is installed on the  Windows  server 2008 machine.

But now we have purchased the Protection Suite Enterprise Edition 4.1.

Is there in our situation some kind of migration possible? What is the best way to install the Protection Suite? Without losing contact with all the alrealdy deployed Endpoint clients .

Please share any documents if anyone have.

Thanks you in advance,

With regards,

Ravi G C
