Configurator Upgrade 11.5.9 to 11.5.10

I am involved in upgrade of Oracle Applications instance from 11.5.9 to 11.5.10.2 which includes configurator too.

In the 11.5.9 version we are also using 2 functional companions. To use these functional companions in 11.5.10, I have to migrate functional companions as configuration Extensions.

While doing this migration when we submit the progrm "Migrate Functional Companions for a Single Model", it gets completed with error. Here is the log of the request :

*************** Begin migrateFCByModel(274960,No) ***************
