When a catalog is downloaded in PARTadmin V12 via the online installation, that catalog already contains the new search indexes for V12. The search indexes for V11 are no longer included. This should be taken into account if the customer intends to continue running a V11 installation in parallel. In this case, the V11 search indexes will no longer be available after the catalog is downloaded. See also Section 5.24.7, “Parallel use of V11 and V12” .
