Hi,
We need more more information to help you on this.
What do you mean by "upgraded an ArcSDE instance (on SQL Server 2005 SP2) from version 9.2 SP5 to 10 SP2"? Do you mean upgrading the ArcSDE software?
The error message you cited from sdedc_SQL Server.log is just a warning upon backward connection. It is expected. The sde_setup.log and the GDBUpgradeN.log (where N is a sequence number) are more relevant.
How did you " upgrade the geodatabase"? from ArcCatalog, or with Python script? Do you see any error from the upgrade dialog? Also, please double check whether you were upgrading the geodatabase through a connection, which is direct connect and as SYSADMIN user.
