Yes, that's what you'll have to do.
By installing the 2003 TS CALs on a W2K Licensing Server, you have
actually downgraded them to W2K TS CALs (since a W2K LS cannot
handle 2003 TS CALs.
Deactivate the W2K LS, install and activate the 2003 LS, install
your 2003 TS CALs on it. Make sure that you decide if you want Per
User or Per Device, and that the TS is configured with the same
licensing mode as the TS CAL type.
If the W2K server is the DC, you might have to hardcode the address
of the 2003 LS into the registry of the 2003 TS (even when they are
running on the same server):

Windows Server 2003 Terminal Services

When everything is working correctly, uninstall the W2K LS
alltogether.

I'm not sure if you will be able to install the same licenses again
on the 2003 LS, since you already installed them on the W2K LS. If
you get into any problems there, use the telephone method and call
the Clearinghouse.
