Migrate SEPM server to new OS

Hi.

I am testing on SEPM migration from Win2003 to Win2008 R2.

I have followed "Disaster Recovery" to do the migration.

After performed Step 4 on disaster recovery to restore the database, a "Management Server Configuration Wizard" appear again.

Do I need to do it one more time (same as Step 2 after installation of SEPM) ??

Or I can cancel it ??

Thanks
