4507 - Loading new image upon reboot

Hi,

I have a 4507RE and just copied over a new IOS (cat4500-ipbase-mz.122-31.SGA11.bin). Since the older image is currently loaded, i need to reboot the switch so that the new image can be loaded. What command do I use to instruct the switch to use the new image and not old upon reboot? But i do not want to erase the old image just incase i need to revert back to it.

I have copied the Sh Vers and Sh Bootflash outputs below.

Thanks.

no boot system
boot system bootflash:cat4500-ipbase-mz.122-31.SGA11.bin
boot system bootflash:cat4500-ipbase-mz.122-31.SGA6.bin
end
wr
reload

Basically, the commands mean boot SGA11 first.  If the IOS fails, boot SGA6.
