Upgrade Guide for UNIX > Planning an Upgrade >

Upgrades from Release 7.x to Release 7.5

---

Your upgrade procedure is almost identical to the other supported upgrade paths to Release 7.5, except for several minor, but important variations. Variations are identified at the beginning of each relevant procedure. Carefully read the documentation and perform every procedure in this guide as instructed. To avoid errors in your upgrade, pay close attention to cautions and notes (shown in the examples below) whenever they appear in this guide.

• Steps to skip. Notes, such as the one shown in the following example, alert you that you can skip a step under certain circumstances.

  NOTE:  Skip this procedure if you are performing an upgrade from Release 7.x to Release 7.5.

• Additional steps to perform. Cautions, such as the one shown in the following example, alert you that you must perform additional steps in certain circumstances.

  CAUTION:  If you previously upgraded to Release 7.x and you already ran the UTC conversion utility, perform the following steps to upgrade the delta columns (those that were not UTC-enabled in 7.x but are UTC-enabled in 7.5).

• Steps with replacement steps. Notes, such as the one shown in the following example, explain the substitution of replacement steps, where applicable.

  NOTE:  Skip this step if you are upgrading from Release 7.x to Release 7.5, because you already created your 32-KB tablespace and bufferpool. Instead, perform the task described in "Increasing DB2 32-KB Tablespace" on page 154.

The instructions that are different for your upgrade from Release 7.x to Release 7.5 are summarized below.

• You may skip the following procedures, since you already completed them during your upgrade to Release 7.x:
  • Data migration procedures in the preupgrade and postupgrade chapters. (See Preparing Application Data for Upgrade and Additional Postupgrade Tasks for Specific Applications.)
  • If your RDBMS is IBM DB2 UDB: Installing stored procedures and user-defined functions. (See Installing the Stored Procedures and User-Defined Functions.)
  • If your RDBMS is IBM DB2 UDB: Creating 32-K tablespace and bufferpool. (See Creating DB2 32-KB Tablespace and Bufferpool for both development and production environments.)
  • Identify and resolve duplicates in your Siebel database. (See Identifying and Resolving Duplicates.)
  • Repository Preparation Wizard to prepare the prior customer repository for the merge. (See Migrate Strings, Merge Labels and Fields, and Merge Templates.)
  • Migrating client configurations to the Siebel Web Client. (See Migrating Client Configurations.)
  • Reapplying custom extensions and foreign key columns on obsolete tables. (See Reapplying Custom Extensions and FK Columns on Obsolete Tables.)
• You may need to perform the following additional procedures:
  • If your RDBMS is IBM DB2 UDB. Increasing 32-K tablespace. See Increasing DB2 32-KB Tablespace.
  • If your deployment is enabled for global time zone support. If you previously upgraded to Release 7.x and you already ran the UTC conversion utility, you must upgrade the delta columns (those that were not UTC-enabled in 7.x, but are UTC-enabled in 7.5). See Setting Up Your Environment to Support Global Time Zone.
  • If you made changes to Release 7.x seeded workflows. During an upgrade, seeded workflows that were shipped with Release 7.x are replaced by seeded workflows that are shipped with Release 7.5. Customizations are preserved and migrated, but you must manually reimplement them in order for them to work properly after the upgrade. See Postupgrade Tasks for Siebel Workflow.
