We need to migrate SEPM from Server 2008 to Server 2012 R2. we have dedicated SQL server that host the SEP db. I see a lot of documentation around, a lot of which seem to contradict themselves. It doesn't help that a lot of the documentation doesn't tell any prequisits such as SQL Server Client tools, dotnet3.5, that you need to make sure you are using the same the software version and nothing new as it updates the sql db schema.
We alreay have had a failed attempt but that was because we installed alater version of SEPM on the new server which updated the db schema and broke everything.
What is the easiest way of migrating? At the moment I am very tempted to just install a new server and anew db and copy the settings across. I have just tried creating a failover server but kept hitting errors on sql and sepm installation so given up.
