Upgrade content server from 6.40 (32-bit) to 6.50 (64-bit)

[Former Member]

Hello!

Our system is currently running on 32-bit windows server. We have planned these changes:

* Change from 6.40 (32-bit) to 6.50 (64-bit)

* Upgrade MaxDB from version 7.6 to version 7.9

* Move from windows server 2003 to 2008

Do you guys have a suggestion for a suitable strategy for achieving this? We were initially thinking about doing the database upgrade first, then performing a system copy before upgrading to version 6.50 on the new win 2008 server. However we discovered that we also need an additional step where we go from 32-bit to 64-bit.

Please advise! Thanks.

Take a full backup of the database (MaxDB) on the source system.

Set up the target server on Windows 2008

Install SAP Content Server 6.50 on the target system.

Restore the backup taken on the source system to the target system.

Reconfigure the content repositories in Tx OAC0 and check Tx CSADMIN

Read these SAP note to know about MaxDB system copy.

Thanks for quick reply. Is there no additional step required for doing a change from 32-bit to 64-bit when doing a restore of the backup on the new target system?

Hi Moye,

I have done a backup and restore of a MaxDB system from 7.6 to 7.8 and it worked and it was done based on the recommendation given in the SAP note.

• You can only import backups of the database instance into systems where the processor works with the same byte assortment (Little Endian -> Little Endian; Big Endian -> Big Endian). SAP Note 552464 describes the permitted combinations. The current SAP MaxDB documentation provides a complete matrix for this. To find the documentation, use SAP Note 767598; for more information, see the glossary entry System Copy.

        You can import backups of a 32-bit system on a 64-bit system and vice versa.

• As of SAP MaxDB Version 7.5, you can also import backups into target systems on which a higher SAP MaxDB version is running.

hello experts,

we're planning to perform the content server migration 6.50 (from windows server 2008 R2) to windows server 2019. And the content server is filebased and there is no database.

i haven't found anything in SAP markplace.

Any ideas?

Thanks

Hi Moye,

Hope you are doing good.

If I am not wrong, Microsoft does not support the upgrade of a Windows operating system if any software - including SAP software - is installed that is not part of the Windows operating system itself.

Hence you can, but it is not supported : the upgrade from Windows 2003 to Windows 2008.

Please also have a look at:

note 192822 - FAQ: 32-bit/64-bit R/3-oracle

note 1476239 SAP system migration to Windows 2008/2008 R2

In case you met any critical problem during the system copy please create message to BC-INS-MIG.

Hi Moye,

The SAP note 514500 - Importing Support Packages for the SAP Content Server is the one you need to follow to update the Content Server to 6.50

Regarding upgrade of MaxDB database you'll find the guide at SAP Marketplace

1983930 - Availability of SAP Content Server 6.50

Check PAM for supported OS and DB for Content Server 6.50.
