[Serusers] Upgrade from 0.8.10 to 0.8.11

[Garey, Tim]

Greetings,

I will be upgrading my Linux SER from 0.8.10 to
0.8.11.

Not having extraordinary amounts of Unix savvy,
is there anything I need to do in preparation for the 
Linux SER upgrade, such as somehow uninstalling 
the old version first? Or can I simply install 0.8.11 
directly over 0.8.10.

I am NOT using SQL and currently using 0.8.10 in a simple
default environment for simple testing.

Thank you,

Tim
