I want to upgrade my SHAREPOINT 2013 RTM version to SERVICE PACK1. Also, i have to upgrade my sql server 2012 to SP2 version. so i have completed the sql server upgrade from 2012 to 2012 service pack2. MY current Version Number of SP 2013 is 15.0.4420.1017
Now, how can i upgrade SHAREPOINT 2013 TO SERVICE PACK1 ? should i upgrade by directly running the sharepoint 2013 SP1 ISO FILE?
