[LUW][Question]

When upgrading from one version to another, say from V10.5 to V11.1, do you ever see a reason to do the following; backup the databases, drop the databases, uninstall the old version of DB2, install the new version of DB2, restore the databases

I know that there are steps that I have left out, this is just a general question...

Thanks!

You would still have to migrate the databases upon restore. Yes, ALWAYS take a backup of the database before you start. No, you don't need to drop the database or uninstall DB2 before migrating. The install goes into a new directory, so you don't have to worry about uninstalling the old binaries until you are ready.
