Error message while upgrading from Sccm 2007 R1 to R2 Beta

I got an error message in recomend checking that

"It is recommended to specify a Fully Qualified Domain Name(FQDN) for site systems in mixed mode Configuration Manager sites. It is required to specify an FQDN for site systems in native mode sites to allow clients to authenticate with site systems."

Solution:

1. Start SCCM Console
2. Click Site Database
3. Click Site Management
4. Click on Site
5. Click Site Settings
6. Go to Site Systems
7. Click on SCCM Server (where State Migration Point is located)
8. Right click on “Configmgr Site System”
9. Click on Properties
10. In the "Specify a fully qualified domain name (FQDN) for this site system on the intranet” change the Intranet FQDN to something like my example here it was MSHOWTO-SCCM I changed it to MSHOWTO-SCCM.EMREA.LOCAL and clicked apply.
11. Solved.
