Question : Need to change root password on production server.. help!

I'm needing to change the root password on a production IBM AIX 5L Unix server and I was hesitant to do that because I'm not sure what could happen. Is there anything I should be concerned of and keep in mind when doing this (things tied to existing root password like processes, startups, etc)? Should I maybe do a search for my password within files? What's the syntax for searching for my password within files (there are about 200GB of files to look thru so this search can probably take days wouldn't it)? Anything else I should look at?

You can search for a certain string in all files with something like

# grep "string" `find /my/dir -type f -print`

String could be either the password itself or it's encrypted string (from /etc/shadow)
