For information about Identity Manager upgrade paths, see Upgrade Paths and Support Policies in Sun Identity Manager 8.1 Release Notes.
The standard upgrade processes supplied with each full Identity Manager release generally upgrade an existing installation from any version of the previous major release.
Remember that each stop in the upgrade path requires a different version of the Identity Manager product. To plan your skip-level upgrade, you must read the Release Notes provided for the Identity Manager product version at each stop in the upgrade path.
For example, if you are upgrading Identity Manager from version 6.0 to version 8.1, you must read the Release Notes for the following versions of Identity Manager:
Version 6.0 and all its service packs
Version 7.0 and all its service packs
Version 7.1 and all its patches
Version 8.0 and all its patches
