Hello We currently run mysql 4.0.14 in MyISAM table format. Server config : Dual P-3 600 1GB of ECC SDRAM 6 SCSI drives 10,000 RPM using RAID 5 Array. OS : RedHat Linux 9. We just realized we really need the adnvaned futures of InnoDB or MaxDB/SAP DB. What would it takes (System preformance, code optimization etc.) to do such un upgrade, and what would you sugest as the most stable / reliable database / table format to suit our needs? (what we really lack right now is the use of foreign keys and replications).
