about upgrading to SEP12.1 RU1 MP1
Now I am running SEP12.1 On Win Server 2003 with SQL Server 2005.
Since I need to upgrade the OS and database version first.
Can I upgrade SEP to newest version by the following steps:
1. Backup the Server Private Key and Database ;
2. Do a fresh installation of SEP12.1 RU1 MP1 on Win Server 2008 R2 with SQL Server 2008;
3. Use the backup to make a disaster recovery;
Or I have to install SEP12.1 first, and make a disaster recovery, then upgrade to RU1(both server and clients), finally, upgrade to RU1 MP1?
Another question is:
How should I upgrade the clients?
A: use SEPM to do a remote push / export a package and install it at the clients side.
B: clients will upgrade the version automatically from SEPM.
A or B ?
If the answer is A, means I have to upgrade the clients to RU1 first and then to RU1 MP1?
Hope someone can help me.
Thanks in advance
