HI,
We are testing the rollback plan for SQL Server 2005 sP upgrade from SP3 to SP4. we have taken the whole system backup (file system ans SBS) before the upgrade, upgraded the SQL to SP4.
Now for rollback test - we restored the system and filesystem taken before the upgrade. However i see the following descrepencies after that
Resource DB is showing SP3 (before upgrade as expected)
SELECT SERVERPROPERTY('ResourceVersion'); --> 9.00.4035
SELECT SERVERPROPERTY('ResourceLastUpdateDateTime');-->2008-11-24 14:27:07.113
However the DB engine is still shwoing SP4 as below
select serverproperty('productlevel') -->SP4
select serverproperty('productversion') --> 9.00.5000.00
REgistyr keys i have checked all says SP3
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Bootstrap\Setup\PatchLevel --> 9.3.4035
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\Setup\Patchlevel - 9.3.4035
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\Setup\version - 9.3.4035.00
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.1\Setup\versin --> 9.3.4035.00
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer\CurrentVersion\Currentversion --> 9.00.4035.00
The datbase is working fine though there is a different version for resource vs DB engine vs registry. But i am not sure what vesion the dadtabases are actually on now.
