Hi,
If I now installed centos 5.3 and for 6 month I buying support from RHEL I can change 5.3 to rhel 5.3? It's possible?

No. The versions for Centos are always higher then RHEL. Therefore unless the updates RHEL versions happen to be greater then the existing centos versions you will never get the updates.

I'd think that it would be technically possible to migrate a CentOS system to RHEL by "reversing" the process documented on the Wiki for migrating RHEL -> CentOS; however, the real issue is likely to be that RH is not going to support it without a fresh RHEL install. Either way the answer is still "No".

Thx for the answered, but the centos have commercial support like RHEL?

CentOS itself is a volunteer non-commercial effort. If you want a paid-support OS RHEL is highly recommended, and CentOS would not exist without them.
There are also companies that offer commercial support for CentOS - google "centos commercial support" and you will find some. One that I happen to know actively participates in CentOS is

Yes. If you get the release rpm files correct and fix your repositories, it will be OK. The Centos versions may be newer at first, but the redhat versions eventually become newer and replace them. I have done this, it is not a big problem. Most of the packages installed will be the same, one a few differences will emerge.
Instead of listening to people tell you they don't think it can be done, you should just try to make it work and see! If you have trouble, you can always reformat the / partition and re-install. As long as you use a simple partitioning system that keeps /home on a separate partition, it is easy to wipe & reinstall without killing your /home stuff.

You really miss the point... The whole reason of using RHEL instead of CentOS is Red Hat's support. If you don't need or have their support, using RHEL is actually *worse* than using CentOS, as you won't have updates.
On the other hand, if you call Red Hat to ask for help to fix an issue and it turns out they find out you "upgraded" a CentOS into a Red Hat server, they will certainly refuse to help you (and would be right to do it).
If you really need Red Hat, you should do a clean install. Period. Upgrading from any other existing Linux install would be the same as aiming the shotgun towards your own foot...

Just in case you want the steps:-
Steps to convert a CentOS5 system to RHEL5
SYSTEM=<hostname> ARCH=i386|x86_64 ssh $SYSTEM rpm -e --nodeps centos-release rpm --import RPM-GPG-KEY-redhat-release rpm -ivh rhn-setup-0.4.19-17.el5.noarch.rpm rhn-client-tools-0.4.19-17.el5.noarch.rpm rhnsd-4.6.1-1.el5.$ARCH.rpm \ rhn-check-0.4.19-17.el5.noarch.rpm yum-rhn-plugin-0.5.3-30.el5.noarch.rpm rhnlib-2.2.6-2.el5.noarch.rpm \ pyOpenSSL-0.6-1.p24.7.2.2.$ARCH.rpm \ redhat-release-5Server-5.3.0.3.$ARCH.rpm
rhn_register
Follow the prompts, after registering the system with redhat:-
yum -y update
Regards
Phil.

Just Like Paul Said, Try it and make it work...I did it too and it worked. CentOS tend to have newer packgakes that RHEL but with constant updates you end up with a full Fledge RHEL 5 system (Server/Workstation).
