The WLP 10.3.2 documentation: Propagation Inventory Compatibility states
WebLogic Portal inventories saved with WebLogic Portal 8.1 or 9.2 cannot be used with WebLogic Portal 10.3.2 propagation tools.
While this implies that a 10.2 inventory can be used, it does not specifically say so. This came up for someone I know who then asked support if one could propagate from a 10.2 environment to a 10.3.2 environment since they wanted to build out a new, clean infrastructure for their upgraded WLP application rather than running an upgrade in the old production environment. The response was quick and short: “No”.
So, being the way I am, I tried it anyway. Works fine. Granted, there are probably many legitimate reasons for not doing this, and I would never suggest it for on-going operations, but as a one-shot move from an existing environment to a new environment it is definitely worth a test run before changing your upgrade strategy.
