Moving a system from MSSQL 2000 to MSSQL 2000 IA64

Question

Hi
We have a R/3 Enterprise 47x110 system running on MSSQL 2000/windows 32 bit. We want to change our hardware to 64 bit. According to platform availability matrix, we have to use mssql 2000 ia64/win2003 ia64 with this release. We want to know which procedure has to be used for moving a system from mssql 2000 32 bit to mssql 2000 ia64?

Hello
Migrating an SAP system from Windows SQL IA32 to Windows SQL IA64 is a fairly simple procedure.
I have performed this migration myself several times.
You need to ensure that your source system (IA32) has the required support pack levels for SQL 2005
I recommend you review 905634, 151603 and 683447.
I would strongly recommend that you move directly to SQL 2005 rather than SQL 2000.  SQL 2005 is fully supported and offers a lot of performance and administration features (such as snapshots).
SQL Data files are compatible between SQL platforms. By this I mean if you do an sp_detach on an SQL IA32 system you can sp_attach them to an SQL IA64 system without any special action.  The files are also compatible between SQL versions, you can detach from SQL 2000 and attach to SQL 2005.  This is described in section III of 799058.
In your case I would:
1.  Make sure you support packs are up to date on source system
2.  Make sure you are using the correct collation 600027
3.  Install 4.7 on your IA64 host from the install CDs
4.  Update your IA64 system kernel to the correct level
5.  Detach the "empty" DB from the IA64 host
6.  Shutdown your IA32 system, stop SQL, start SQL and then stop SQL
7.  Copy the datafiles and log files to the IA64 system
8.  Attach them to your IA64 SQL 2005 system
9.  Run the SQL Tools utility
10. Start up your 4.7 instance
11. Check SM21, ST04, SICK and DB02
12. Reschedule your backups and DBCC
This procedure should work and should be quite simple to implement.  You can leave you IA32 system untouched, so if you experience any problems you have a fall back position (ie. just restart your IA32 system - nothing has changed on you IA32 system or its database).
I recommend you obtain the official SAP SQL 2005 CD, it includes SP1 and has a useful script call SQL4SAP.VBS that sets a lot of options for you automatically.
Check 879941 - you may need to adjust the torn page setting and auto_update_statistics_async settings or you will get red alerts in your CCMS tree.
For other people out there who use Java systems (EP, XI etc) you <b>will almost certainly</b> have to update your JDBC drivers. See note 639702. 
Hope this helps, let me know if you have any questions.
Goodluck
