Well I hope so, because we just signed a contract to have them convert us.
The thing they said was that they did not support you if you did the convert from windows to unix by yourself. but we would be supported if we had them do it. That you had to becarefull because the location of the files is different on windows vs unix (duh!) and that you had to be sure you got them all in the corrrect place.
Our first plaining meeting is tomorrow to go over license requreiments for the upgrade and what I need on the new master/media's for the convertion in way of disk space and tuning issues.
