Hello,
I have suggested the below Steps for Migration from SAV 10 To SEP 11.0.6005 (Normally, Customers would like to Install SEPM on either the same Server where the Symantec System Center is Installed OR on Different server computer)
Before you start with the Procedure of migration, make sure, you disable the Security Password to disable SAV clients from SSC.
1) Install Symantec Endpoint Protection Manager,
2) Create new SEP 11 packages for new Deploy on all the other machines.
3) Deploy the packages to all SAV 10 client machines, which will migrate all the clients to SEP (this could be done either with the help of "Migration and Deployment Wizard" OR "Find Unmanaged Computers"
Till the time the migration is over, the clients which haven't migrated from SAV 10 will communicate to Symantec System Center 10.
4) Once all the machines have been migrated from SAV 10 to SEP 11.6005
(Except on the same server machine where the Symantec System Center 10 is installed, as SEP will not get installed till Symantec System Center 10, SCS 3.1 is uninstalled.),
5) Uninstall Symantec System Center 10, SCS 3.1 on the server
6) Install SEP on the same machine where the Symantec System Center 10 was uninstalled.
