moving one database

I will be attempting to move our training database to another disk soon. I would like to use dbexport and dbimport, and have created a separate dbspace comprised of two chunks for import. Currently both databases are in the same dbspace. I chose to move train into a separate dbspace as that way we have the option of restoring only one of our two databases from tape. My questions are: 1) By using dbexport/dbimport, I understand that the table permissions for users will be preserved, but are there any other items that will not be preserved that I will have to recreate after I do the import? 2) What I understand is that I will not need a separate engine, but will I need to setup separate shared memory or other structures? 3) Will our current ontape still function to archive both databases, even if they are in separate dbspaces? 4) For those in the CARS list, will that affect any future updates in CARS software?
