Depends, if you want to lose that functionality than yes you could reboot the switch.
If you want to keep those functions, then don't.
Go look for and add the license again.
Keep in mind that a port down event on the ports (that where unlocked with the license), will disable them until the license is present again.

Thank you for your answer.
The installed 7800 switch only uses 4 FC ports (Port No.0~3) and GE0.
In this case, is it ok for FC and GE traffic when I remove the upgrade license key?

By removing the upgrade license the unit reverts back to a 7800 4/2.
A 4/2 unit has FC0-3 and Ge0 and Ge1 enabled by default.
So Yes you could remove the license.
But don't think you can use it in another 7800 or any other product.
Licenses are bound to the switch's wwn.
