Windows 2003 to 2012 -- no 2008 need ?

An article said only the below option #2 is doable ?
Is this a true statement ?
If not, I will do option #1

Option #1
 1. add new Windows 2012 R2 64bit domain controller server into domain
 2. drop old Windows 2003 R2 32bit domain controller server from domain

Option #2
 1. add new Windows 2008 R2 64bit domain controller server into domain
 2. drop old Windows 2003 R2 32bit domain controller server from domain
 3. upgrade new Windows 2008 R2 64bit domain controller server to 2012 R2

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You do not require to have a 2008R2 DC in your environment if you are planning on upgrading to 2012R2 DC. All that is required is the following...
- server 2003 forest/domain functional level
- Adprep the forest/domain (this is automatically done during the promotion of the first 2012R2 DC
- Once you have promoted the DC 2012R2, you can move the roles and decommission the 2003
- configure your PDC Time Source on the new DC
- At this point you can then raise the forest functional/domain functional levels to 2012R2

Post steps would be...
- configure DFS-r replicaiton for sysvol

- transfer any other roles off of this server i.e. DHCP, remove DNS role (as this is not removed automatically)
etc.

"An article" was incorrect. I recommend sticking to authoritative sources for system requirements, such as TechNet. Or use a site's points system such as experts exchange or Microsoft forums to help gauge the reliably of the person giving advice. Or you'll waste time following bad advice. Or worse, waste time song if every piece of advice given is good and no good way to judge if the person answering even knows.

Along with what has already been stated here, there are a couple of potential gotchas to look out for:

1.  You may have to modify the component services on the 2003 DC before ADPREP will successfully run:

2.  Kerberos authentication can fail intermittently (Microsoft has a hotfix for this issue) -

Option 2 is doable.  It's a waste of time, but doable.  Could you cite the article that you're basing this on?  It should either be corrected or your interpretation should be corrected.
