Can I reconfigure/reinstall em for dbconsole

Question

I moved my database from one server to another. The database move was smooth but I couldn't use my dbconsole. It complained about the emkey.ora. I copied the emkey.ora from the old server to the new server but it seems the em repository has data for the old server so even though I connected to the correct host the screen is displaying the old hostname.
Can I reconfigure or reinstall em?
