NT 4.0 Server, Hardware Raid 5, C: is primary partition, E: is extended partition containing application and data. User wants us to install 2000 on the C: partition, leaving the e: partition in tact. User will re-install applications on the e: drive and wants to know if the application will recognize the data files on the e: drive. Application and data are inter-twined so user cannot separate data from application before migration. Is this upgrade scenario possible? Recommended? Any errors or issues that I can except? Thanks for any help.
