Stechies

You want to perform an upgrade in combination with a system conversion to Unicode.

1. For which source and target releases is the Combined Upgrade & Unicode Conversion (CU&UC) supported?

2. Is the CU&UC supported for all code page configuration types?

3. Is the CU&UC available for all customers?

4. Are there any hardware regulations for this project?

5. What support packages, patches and corrections I need?

Below are the solution which is step by step explained:
 

1. For which source and target releases is the Combined Upgrade & Unicode Conversion (CU&UC) supported?


              General Information:

              The CU&UC is only available for upgrades to target release NW 2004s and higher.
It is not available for upgrades to lower target releases.

 

  • Target Release NW 2004s SR0:

           Only source releases R/3 4.6C and R/3 4. 6D are supported and available for all customers.

  • Target release NW 2004s SR1 and all following SRs:
    • Source releases that are supported and available for all customers:
      R/3 4.6C, R/3 4.6D,
      R/3 Enterprise 4.70 Core with Ext. 1.10 or 2.00, and
      SAP ECC 5.0.
    • All other SAP products based on the following source releases are supported and available for PILOT CUSTOMERS:

                    SAP_BASIS 4.6C, SAP_BASIS 4.6D,

                    SAP_BASIS 6.20, and

                    SAP_BASIS 6.40.

                    If you want to become a pilot customer, please contact globalization@sap.com.

              Note: For MDMP systems on source release Web AS 6.10 and on source releases lower than R/3 4.6C a different procedure called "Twin Upgrade & Unicode Conversion" ("TU&UC") is available on pilot project basis. 

              The TU& UC procedure is only available for MDMP and Ambiguous Blended Code Page systems.

 

  1. 2. Is the CU&UC supported for all code page configuration types?


              The CU&UC is supported for:

  • Single Code Page configurations
  • MDMP configurations
  • Unambiguous Blended Code Page configurations
  • Ambiguous Blended Code Page configurations which meet the requirements listed in SAP 818374 (minimum Support Package and Kernel patch levels, special parameter settings, etc.).
  1. 3. Is the Combined Upgrade & Unicode Conversion (CU&UC) available for all customers?


              For target releases NW 2004s SR0, SR1 and all following SRs the CU&UC with source releases R/3 4.6C, R/3 4.6D, R/3 Enterprise 4.70 Ext. 1.10 and 2.00, and SAP ECC 5.0 systems is released for all customers. This applies to all supported code page configuration types listed in section 2.).


               Note: We strongly recommend that this upgrade is done by a certified SAP Technical Consultant with experience in converting systems to Unicode. Please contact globalization@sap.com for more information.


              For all other SAP products based on NW 2004s SR1 onwards with source releases SAP_BASIS 4.6C, SAP_BASIS 6.20 and NW 2004 the CU&UC is available on pilot project basis (see 1.)



The Internationalization Team (BC-I18-UNI) will monitor the upgrade process and provide quick development support via OSS messages. For enhancement investigation, we kindly request customers to send an e-mail with the following information to internationalization@sap.com:

    • database size before and after the conversion
    • export and import runtimes
    • methods used for downtime reduction

 

  1. 4. Are there any hardware regulations for CU&UC?


              In some cases there might be additional hardware required for a Unicode system (compared to non-Unicode). The size depends on several factors, for example the database encoding format (UTF-8 vs. UTF-16), the code page and language settings (MDMP vs. Single Code Page) before the CU&UC, use of double byte languages like Japanese, and more. SAP 73606 provides detailed information; please refer to the documents attached to 73606.

 

  1. 5. What support packages, patches and corrections I need?

      867193 contains up-to-date information about required support pacakges, patches and corrections.
