Moving Sharepoint Portal Server 2003

For example from a Two Server farm to Standalone; or from development to production.Install Sharepoint on the destination server but do not create a portal site instead chose to restore the site. Specify the content databases it is better to restore them on the machine first. This way you can chose any topology you like on the backup machine.
One Issue: I ran into one of my (100+) sites did not come up on back up portal.After troubleshooting for a while I found that the field (Id) in the Sites Table in _SITE db and the file (SiteId) in the Sites table in SPS_config did not match I changes the SiteId (SPS_conifg ) the site came up like a charm
