There are two paths to upgrade the Repository-based Java CAPS components from previous versions of release 6. In the first method, you install Java CAPS 6.2, export all projects from the older release 6 environment, and then import them into the new 6.2 environment. In the second method, you install Java CAPS 6.2, install a patch to update the older release 6 Repository, and then connect to the older Repository from the Java CAPS 6.2 environment. With the second option, you have a side-by-side installation, but you do not use the new Repository. Instead you continue to use the existing upgraded Repository.
The patch to upgrade the Repository is included on your installation media in patches/patches_ml.zip. The patch file is named 6836560-01-REP.zip. For full upgrade instructions, see Upgrading to Java CAPS 6.2.
