Upgrade MAXDB 7.5 32 Bit to 7.5 64Bit (X86_64)

[andreas_lorenz2]

Hello all,

we want to upgrade from 32Bit to an 64Bit-x86 MAXDB-Version.

What's the best way to do this?

Actually we run 7.5.0.28 on RHEL3.

My thought is now to

1. Down SAP and MAXDB

2. Update RHEL3-32Bit to RHEL4-64Bit

3. Update Maxdb 7.5.0.28 32Bit to 7.5.x 64Bit with SDBUPD. Is this even possible?

4. Update SAP-Kernel

Is this a corect way or do we need to install a complete new SAP and then do a recover?

Bye

Andreas

Hi Andreas,

that would not be a standard way of upgrading when switching both OS- <b>and</b> DB-version.

DB-side recommendation:

I would suggest following note 129352 (i.e. backup-recovery strategy). Ofcourse you know that you will have to test this on a Test-system before upgrading your Prod. system.

Regards,

Roland
