Upgrade + migration from nw04 on windows 2000 to nw04s on windows 2008

Former Member

Dear all,

I need to upgrade and migrate my nw04 java system from windows 2000 to nw04s on windows 2008.

From the PAM I can see that NW04 is not supported on windows 2008 and that nw04s (7.0) is not supported on windows 2000.

So, which is the correct upgrade path? Do I need an intermediate win 2003 server which is supported from both the releases?

Thanks and regards in advance

Federico

Hello my friend

This will be a very interesting project for sure. As you know, kernel 640 is not supported on win2008 and 700 is not supported on win2000, so here there must be a win2003 as a transition platform for this upgrade+ migration, not to mention migration from 32bit to x64 is also involved. You didn't mention the DB versions in source and target systems, as well as the SAP product you're trying to go with. Here's a brief checklist right now for what I can think of, once you're back with more details then let's make it intact:

I assume your source OS/DB is win2000SQL2000 32bit, target one is win2008SQL2008 x64.

1. Install a win2003 x64 server and SQL2000 32bit;

2. Install a new SAP instance same as your source system release in 32bit compatible mode;

note: if the system being migrated is BW, then be aware of that you might want to bring new features in SQL2008 of row compression and table partitions.

3. Detach the source DB from old SQL2000, and attach it to new SQL2000; some post configuration for DB copy will be required (STM tool). Now you've finish a migration from win2000 to win2003 32bit;

4. Start upgrading NW04 to 7.0, 640 to 700, find details in upgrade guide; Now you have your 700 instance on win2003 x64+SQL2000 32bit;

note: since release 701(700 EHP1) is available now, which you might want to upgrade instead of 700.

5. Change the collation 850BIN2 for SQL2000 32bit, detach DB;

6. Since migration from 32bit to x64 cannot be done smoothly, now you have to uninstall everything and reinstall win2003 and SQL2008 x64, followed by a new 700 or 701 instance;

7. Attach the source DB, post configuration for DB copy will be required (STM tool); Now you have your 700 or 701 instance on win2003 x64+SQL2008 x64;

8. Detach the SQL2008 DB;

9. Now go to your target win2008 OS, install SQL 2008 x64 and new 700 or 701 instance;

note: there might be some restrictions for NW 7.0 on win2008, go with the latest release (SR3 or newer).

10. Attach DB to this final OS/DB version: win2008 x64+SQL2008 x64, post configuration for DB copy will be required (STM tool).

Helpful?

Regards,

Effan

I would do this:

open a message with SAP and ask them if they accommodate you by using nw04 on Windows 2008 for a few weeks until you complete your upgrade. If SAP says yes, your problem is fixed.
