Need a Guru to interpret a syslog output from a router

OK, so I just received my super cool 2821 with 2 gig etherports and 2 WIC 1Ts.. I was cleaning out
the running config but when I did a copy ru st I got this:

Feb 7 01:49:10.771: %SYS-5-CONFIG_I: Configured from console by console
R3#copy ru st
Destination filename [startup-config]?

So I did a sh flash cuz I thought there was a second IOS on the flash, but the output above
does not show that, I'm guessing the run config was copied into a new uploaded iOS? Or something like
that : am I making sense?

Thanks Gurus!!!

2821 is running ios x, wr mem, running is saved to startup.
Install new ios x+1, wr mem, Warning: Attempting to overwrite an NVRAM configuration previously written

Some config can be lost on the translation, so its a good idea to copy the existing startup to a text file and do a compare afterwards. You might notice some new default commands, command syntax change. Normally you don't see too many issue's upgrading, downgrading is more troublesome.
