Problem with Server Settings Migration Wizard
A bit of an oops moment from the Enterprise Vault world which is described in this following technote:
It is an issue relating to using the Server Settings Migration Wizard and in fact using it to migrate EV 10 to another machine with EV 10. The Migration Wizard can't handle (at the moment) EV 10 as a source. It is likely to be one of those that was just never thought of during the design and building - after all most people will use the Migration Wizard to move from EV 9 to EV 10.. not EV to EV 10.
Hopefully it will be something which gets addressed in the near future.
