Double-check that your MSFC's IOS running-config and startup-config are the same. If they are not, then copy each to a separate file for future reference, and copy running-config to startup-config.
Catalyst OS config changes are immediate and persist through a reboot. To be safe, get a copy of "show config" and "show config all", to separate files. Whatever's missing from the "show config" are the default settings; you can see what these are in the "show config all" listing.
If you're really paranoid, do a "show version" on the MSFC's IOS and the CatOS to note the version numbers; and copy the IOS and CatOS software to a TFTP server, just in case.
Having said all that, I usually just copy the MSFC's run to start and then power off and on. Never had a problem with a 6500 chassis. But in your situation, after 3 years of uptime, I would sure want to be able to recover quickly from any kind of problem. Three years of uptime -- WOW!
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
