Cleaning up AD for installation of new 2012 domain controller

Hello,
I am replacing a 2003 server with a 2012 R2 server.
Can anyone give me some advice on what I need to clean up in AD before adding the new server, giving it the domain controller role and replicating?

I've deleted all unneeded users and see a lot of computers that are no longer in use, so I'll be deleting them.
Is there anything else I should look for?

There is nothing that needs to be cleaned up.  Maintenance of your AD to remove unused accounts, etc. is another topic but it's not required for introducing a new DC.

Thanks footech.

I guess what I'm asking is what should I remove to maintain my AD.
I realize that I could introduce the new DC,  let everything replicate, then do the maintenance later,  but what I'm wanting to do is clean up AD before adding the DC.

This is a very simple domain. I'm thinking all I need to do is remove unused accounts, computers and clean up DNS (not that I need to do that first either) by removing records that aren't applicable anymore. I'm looking now and there are a lot of them.

So I guess my question is, other than users and computers, is there anything I need to remove to keep AD in good shape?

Thanks,

Pretty much anything you create manually is a candidate.
Users, computers, groups, OUs.  It's much less common for an OU or group to become unneeded however.
If you've had other DCs or sites, it's not a bad idea to check for them as well.
DNS deserves it's own consideration.  Run checks like dcdiag /v /test:dns, get familiar with the _msdcs zone, learn about scavenging and then turn it on.
