2. Installation and upgrade

2.1 Can I install a different version of the database on a single server?

Sure, you can.

On a Windows platform, if you are using DB2 UDB version 8, you must first install

Earlier version, and then install a new version. The new version must be installed in a different directory.

For example, you cannot install DB2 UDB version 8 after DB2 version 9 or DB2 version 9.5. You need to first install DB2 UDB version 8 and then install DB2 version 9 or DB2 version 9.5 in a different directory.

For DB2 version 9 and DB2 version 9.5, you can install it in a different directory. For example, you can install DB2 version 9.5 in a directory, and then install DB2 version 9 in a different directory.

2.2 If I already have an instance of DB2 version 8.2, can I use the same instance on DB2 9.5?
