DB2 Connect™ Version 9.5 servers supports the migration of DB2 Connect instances, and any existing transaction manager and DB2 Connect federated databases created on DB2 Connect Version 9.1 or Version 8 servers.
Since DB2 Connect server products are host database connectivity servers, the only databases that can exist within a DB2 Connect server instance are transaction manager databases and DB2 Connect federated databases. The DB2 Connect transaction manager database stores transaction state information for DB2® coordinated transactions. The sole purpose of DB2 Connect federated databases is to contain information about data sources.
On Linux® and UNIX® platforms, you should manually migrate your DB2 Connect instances after installing DB2 Connect Version 9.5. All the remote nodes and databases that you cataloged on the DB2 clients refer to these instances. If you create a new instance, again you will have to catalog nodes, DCS databases, and databases on the DB2 clients that existed in the Version 9.1 or Version 8 instance.
On Windows® operating systems, you have an option to automatically migrate an existing DB2 Connect Version 9.1 or Version 8 copy during installation. Your DB2 Connect instances are automatically migrated. Alternatively, you can install a new copy of DB2 Connect Version 9.5 and then manually migrate your DB2 Connect instances.
This procedure describes how to migrate by installing a new copy of DB2 Connect Version 9.5 and then migrate instances and any existing databases. To automatically migrate an existing DB2 Connect Version 9.1 or Version 8 copy on Windows, follow the same steps specified in Migrating a DB2 server (Windows) .
For DB2 Connect Version 7, migrate to DB2 Connect Version 8 first. Refer to the following topic for details: http://publib.boulder.ibm.com/infocenter/db2luw/v8/topic/com.ibm.db2.udb.doc/conn/t0008566.htmTo migrate your DB2 Connect server:
$ db2cfexp cfg_profile backupThis profile contains all of the instance configuration information, including the database manager configuration and registry profile because the option backup is specified. You can use this profile to recreate your connectivity configuration if necessary.
