Importing backup images of tapes from other netbackup domain

We have few tapes from a legacy netbackup environment and are trying to import the backup images of these tapes into new environment. For few tapes, 1st level of import shows successful and when I search/browse for images, can't see anything.

If I perform the following steps, will the 1st level impot be successful ?

a) bpexpdate -m mediaID -d 0 and

b) delete the tape from EMM database and

c) Run inventory of the library

d) perform a 1st level import again,
