Hi,

First i upgraded my SEPM 12.1.5 RU5 to 12.1.6 RU6, after successfully upgraded to 12.1.6 RU6 i run sylink replacer file for replacing the sylink file on clients (all clients showing offline in management console) . I surprised after run the sylink replacer file from server end , all client still showing offline in management console. Clients are able to ping the server.

When i tried to replace the sylink flie manually from client end. it work.

Any idea ?

Sylink replacer is not integrated with Client deployment wizard. You were running tool separately or through Client deployment wizard?
