For users of an earlier version of the database manager, installing Version 7 Release 1 means loading the new code by running one or more IBM supplied programs, and migrating any existing databases. This section highlights the considerations that you should be aware of when doing this.
The topics are grouped by the release level of the database that is being migrated. Start at your release level and read to the end of this chapter. For example, if your database is Version 3 Release 1, you must review all the topics; if it is Version 3 Release 2, you need only read from that topic to the end of the chapter.
A database that is migrated keeps its existing HELPTEXT dbspace, which may not be large enough to support the Version 7 Release 1 HELP text. The size required for this dbspace depends on the number of national languages for which you have HELP text. It should be:
2,304 pages x number of languages installed.
This dbspace can be increased at any time before you install the current HELP text. For information, see the DB2 Server for VSE & VM Database Administration manual.
If users are running their applications under the DRDA protocol, some database manager facilities are not supported. For a list of these restrictions, see Appendix H, DRDA Considerations.
