Hi,
We are trying to upgrade SQL Server from 2005 SP /Developer 64-bit to 2008R2 /Developer 64-bit. At the last step before starting installation I get an error "Feature upgrade failed". Looking into this error, it seems that this occurs when trying to upgrade developer --> standard/enterprise OR 32-->64 bit but this is not the case for us.
The DVD that we are using is burnt from the file: en_sql_server_2008_r2_developer_x86_x64_ia64_dvd_522665.iso From Download area
for my MSDN subscription. This DVD was used on a test machine to upgrade developer-->developer successfully... When given the option, I can't choose between enterprise and developer and can only choose between free (express, etc.) and other edition. So
I choose the other option and a key is detected coming from DefaultSetup.ini:
;SQLSERVER2008 Configuration File
[SQLSERVER2008]
PID="GYFXX-XXXX..."
Any ideas where to look and what to look for? One hint is that the license agreement is titled "SQL Server 2008R2 enterprise" but this might simply be for the license agreement...
Thanks a lot for your assistance!
