Endpoint Protection

I am running SEP 11.0.2010.25

I need to update to RU5.  I went to our support site yesterday, and downloaded, but it's the full program, not just a service pack type install like I was hoping.  I have a couple of concerns:

1)  When I run this on my existing AV box, will it recognize that I already have SEP 11 installed, and just do an update/upgrade to RU5?
2)  Will I have to recreate the install packages that I already have, since they'll be a different version now?
3)  Will I lose any of the configurations, settings, or policies that I have in place now?

I need to know this information as quickly as possible, as I'm supposed to be doing this upgrade this morning.

Thank you very much for any advice/tips that you can offer.

Yes wil run the upgrade
2)  Will I have to recreate the install packages that I already have, since they'll be a different version now?
Yes you have two options, you can create package and use or use autoupgrade feature.

Nope you want everything will be in place.

That looks like the exact document I was hoping to find.  Thanks Rafeeq :)
