Best approach to upgrade MaxDB AND move to new OS release

[Former Member]

What would be the best approach to upgrade Contentserver MaxDB 7.5 on W2K server (32-Bit) to MaxDB 7.7 on Windows 2008 Server x64 (R2?)?

1. a) Upgrade MaxDB on the existing installation

b) Create a complete backup

c) Install latest release on new machine

b) recover with backup from existing installation on new machine

2. a) Create a complete backup from existing installation

b) Install same release on new machine

c) recover with backup from existing installation on new machine

d) upgrade to latest release on new machine

Both approaches share the problem that you have to run a OS/DB release constellation that is not released according to SAP PAM. The second approach has the advantage that the source system will not be touched and is still available in the original status if something fails. But the main issue is the compatibility question (7.5 not released for W2008, 7.7 not released for W2K)

Any suggestions?

Thanks,

Matthias

Hello Matthias

the MAXDB version 7.5 is not released on W2008, I recommend to go with 1 option.

Please see SAP Note No. 919224 , SAP Note No. 919225 and

SAP Note No. 1399009 - Content Server 6.40 on Windows Server 2008

Do you have Content Server 6.40 ?

Thank you and best regards, Natalia Khlopina

Natalia,

thanks for your answer.

> Do you have Content Server 6.40 ?

yes.

> the MAXDB version 7.5 is not released on W2008

neither is 7.7 on W2K.

> I recommend to go with 1 option.

Which would be this one:

>>1. a)Upgrade MaxDB on the existing installation

So can I upgrade to 7.7 on W2K though it is not released for this combination?

Best Regards,

Matthias

Now that 2008 R2 is released with MaxDB 7.8 the question remains the same... . Any ideas?

Hi,

please check note 1399009 regarding Content Server 6.40 on Windows Server 2008/R2.

I would suggest upgrading the source MaxDB from 7.5 to 7.6 and then backup/recovery to the target system 7.6 and then upgrade to 7.8.01 (better: 7.8.02 once it is released).

Kind regards,

Thorsten

Hi Mathias,

after replying to your question in 'Recover Content Server MaxDB from a different DB release', let me add that if you are running at least MaxDB 7.5.00.50, you could directly backup/recover to 7.6 or 7.8. Personally, I think there is not much difference between upgrading from 7.5. to 7.5.00.50 and then recover to 7.6 on target system or upgrade from 7.5 to 7.6 and then recover on target system.

Best regards,

Thanks,

that answered my question

Hi,

stupid question:

Is win2008 r2 capable of 32bit? And if not, can I restore a 32bit db into a 64bit db?

Hi Jan,

on 64 bit Windows you should use a 64 bit database version (afaik 32 bit cannot even be installed on a 64 bit OS as the installer rejects ist).

64 bit or 32 bit does not matter for backups, this will always work.

But keep in mind that the recovery must be performed on a OS/processor type that is binary compatible to the backup (littel/big endian type), e.g. Windows and Linux usually are compatible (both little endian).
