SEPM Clients not showing up in the SEPM console.

Implementing SEPM client test installations and I have two clients that on the client end say they have received the updates, but do not appear in the SEPM console. They get the shield in the icons box, but no green dot. From these clients, I can ping the SEPM server, but they read that they cannot connect to it. The clients have been rebooted. All seems well on the client side, except they cannot connect to the SEPM server.

The 2 workstations and 1 laptop that installed successfully and appear in the SEPM console did not have a previous installations of SEP. Whereas, the 2 unsuccessful installations both had previous installations of SEP from a different SEP server, which will eventually be decommed.

First question : Should "Automatically uninstall existing security software" be enabled to remove these previous SEP client installations before installing a newer version?

Second question: Can you suggest any steps I should take to get these clients to be recognized by the SEPM server, ie, remove previous SEP installations before installing upgraded SEP versions from a different SEP server?

You can still choose to automatically uninstall existing third-party security software when you deploy a client installation package. Otherwise, you must uninstall third-party security software before deployment. However, need to note the supported and unsupported migration path

For 12.1, can catch http://www.symantec.com/business/support/index?page=content&id=TECH163514
You may want to install Symantec Endpoint Protection from scratch without migrating the legacy software. If you skip the migration, you do not import the legacy settings.

To skip the migration of legacy products:

Uninstall the legacy virus protection software from your servers and client computers.

During Symantec Endpoint Protection Manager installation, do not select the migration option.

After initial product installation, use Symantec Endpoint Protection Manager to adjust the group settings and policy settings.

Deploy the Symantec Endpoint Protection client to the unprotected legacy computers.
When to import legacy settings during migration from Symantec AntiVirus to Symantec Endpoint Protection

The clients may still have old Sylink file ( communication file)

another is existence of an old entry about proxy server remains in the registry

In case, you are running SEPM 12.1 RU2 and above, check this Article:

Hopefully also not the issue when doing cloning
