Global Catalog not found

I am replacing a windows 2003 primary domain controller that was running global catalog. I went through all of the migration steps like (FSMO roles, global catalog, etc) When I made the new server a global catalog and removed global catalog from old server, I am not sure if it replicated to the new server yet.

If it did not, what can I do to correct this? Can it just rebuild catalog on it's own?

Is this a single domain controller?  Do  you have other GCs on the network. Just trying to get a sense of your domain/forest structure
If you type
dsquery server -forest -isgc how many GCs in the forest?
Thanks

This is what I get when I run that command. It actually does says the new servers name, does that mean things may be ok? (i ran this from both old server and new)
 
C:\Documents and Settings\Administrator>dsquery server -forest -isgc
"CN=SHCC-SRV,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=
SHCC,DC=local"

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

.  The GC contains a partial representation of every object in every domain in a forest. So in your  single DC domain/forest the info is all there.  Sounds like you already made it a GC
You really should have at least two DCs though.  What if your current DC crashed hard?  If you had a second DC that would really help and your users wouldn't have the downtime.
Thanks

The new server is definitely marked as a Global Catalog in AD Sites and Services, but what if it didn't replicate all data from old server?

You can check for event 1119 in the directory service logs
or check the registry
http://technet.microsoft.com/en-us/library/cc961811.aspx

Verify if the Global Catalog Promotion Complete registry entry stored in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters\ is set to the value 1. If it is, then the computer is advertising as a Global Catalog server.
Is that old box still a domain controller?
Thanks

I looked in EVENT VIEWER / DIRECTORY SERVICE and do not see anything saying global catalog has been repilicated, but when I look at the registry key you noted, it has a (1) next to Global catalog promotion complete

Yes, the old server still is a domain controller

ok then you are ok, but I'd make that other DC a GC too.  Take a look at the first bullet point about the DC/GC

Now I am seeing that I cannot demote old server from being domain controller, it says it can't find any other DC's within domain

If the demotion is not working you may have to remove the DC by using the metadata cleanup process
