How to move DB2V8 32bit + 46C 32bit to RHEL 4 x86_64 + DB2V8 64bit
A client of mine bought new hardware with RHEL 4 x86_64, so I must move their existing Linux 2.4 IA32 / DB2V8(FP14)_IA32 / 46C systems to the new hardware, with the end result being RHEL 4 x86_64 / DB2V8(FP14)_x86_64 / 46D_EXT_64.
My problem is, after going through all the DB2 and 64bit migration notes, is what DB2V8(FP9) installation kit should I use to prepare the new hardware? I first have to install 46C SR2 with DB2V8(FP9) on the new servers, but there are IA32, Linux26_IA32 and x86_64 versions for DB2V8. Can one install the x86_64 version now, copy/restore the old DB2 database to the new installation and migrate the database to 64bit, or should one first install DB2V8(FP9)_Linux26_IA32, copy/restore database, migrate to 64bit and then upgrade to DB2V8_x86_64?
Please help, I want to use the solution with the least amount of steps (or problems!)
