The GP faults described in the NGERROR.TXT are simply follow-on consequences of the SQL errors; it will help to see those original SQL errors since they describe what has actually gone wrong.
That said the the most likely cause for those is a failure of some kind during the upgrade process; during the upgrade, the V2.x installer has to transcribe all the data out of your original database into one that is laid out for the new server and console. Perhaps this process has failed somehow; or, perhaps one other alternative is that you have transferred your original v8.2 database - the SYMANTECGHOST.DB file - by hand into your new GSS 2.0 install (which cannot possibly work - the database transcription process performed by an in-place upgrade is absolutely necessary).
Once we can be sure (from the SQL error) quite what has gone wrong we can suggest how to resolve it; usually though, that will involve recreating the v8.2 install and re-running the in-place upgrade so that it successfully transcribes your old data into a database laid out for the GSS 2.0 product.
