Migration BE12 (CAS/Managed) to BE14

Hi,

the situation is as follows:

1xCAS with W2K8R2 64bit and BE2012 SP3 & HF213186 installed

1xManagedBackupServer with W2K8R2 64bit and BE2012 SP3 & HF213186 installed

sharing an Overland-Library with 3 TapeDrives.

to migrate I assume the followin steps:

-) install SP4, HF215906, HF216746, HF217347 on both CAS and MBS

-) stop the communcation to the MBS and install BE14 on the CAS

-) stop the CAS

-) install BE14 on the MBS

-) reboot both server (CAS & MBS)

I'm interested in your experience and if I missed something, Thanks for your input
