I'm planning to upgrade version 5.0 to 5.1 and I have gone through with cisco document as well but can any one tell me if there is any known issues during upgrade or better way to make that upgrade smooth?

Hi Nomair,

No, the documented way is the way to go. If you get into trouble, either post here or open a TAC case and we can help!

Dear Faisal bhai,

'Im planning as below:

Promote secondary as primary and deregister old primary/log collector and make is standalone.

Upgrade old primary whihc is now standalone and after upgrade promote it again to primary one.

Then deregister secondary and make it standalone and upgrade it.

Sounds like a plan???
