That would probably be a good idea if they are the same MV's.

It might not be too important if you are going to recreate the MV's anyway, but it could

  1. use up a lot of disk space
  2. generate a lot of errors
  3. both

When you import MV's, the refresh jobs have a tendency to be created in the account of the importing user or SYSTEM, I forget which. After the import you will want to check for strange refresh jobs that don't work.
