Component : Upgrade SAP System with DB2 Universal Database - DB2 Universal Database for Unix / NT

Summary :
This SAP Note details the migration process of 32-bit SAP systems to a 64-bit architecture on AIX, Solaris, and Linux x86_64. The migration is feasible with the 64-bit 4.6D kernel supported for specific SAP versions including R/3 4.6B/C, BW 2.0B/2.1C, and APO ≥ 3.0A. From SAP Basis Release 6.10 onward, utilizing a 64-bit database on these platforms is imperative as 32-bit kernels are unsupported post-2003. Migration prerequisites stipulate a minimum DB2 Version 7; however, for combined use of 32-bit and 64-bit applications, DB2 Version 8 is required. The note suggests thorough system backups pre-migration and adhering to specific configurations detailed for DB2 installations based on AIX adjustments.
