Do I need to import?

Hello,

I'm new to using Backup Exec, specificly we have ver. 2010.  My question is after swapping tapes do I need to do an import?

The steps I've done so far are.

1.  Unlock tape dirve

2.  Removed full tapes

3.  Put in new tapes.

4.  Lock tape drive

5.  Do an inventory

6.  Put new tapes into scratch.

Is there a step I have missed?  Do I need to import the tapes?

Thank you
